Description

Fault location and isolation method and detection equipment

technical field

The invention relates to the field of communication technology, in particular to a fault location and isolation method and detection equipment in a low-power distribution communication network.

Background technique

The communication methods of devices in Internet of Things applications are divided into wired and wireless methods. Among them, CDMA/GPRS/Wi-Fi communication based on mobile communication technology: simple deployment, moderate speed, low investment and operation costs, and more and more attention .

The new communication system generally considers the use of high-speed, reliable and cost-effective optical fiber communication on important communication trunk lines, while the last hop communication to general terminal equipment can use GPRS or Wi-Fi, which is flexible, convenient, moderate in speed, and low in investment and operation costs. Wireless communication method.

In the wireless communication mode, when there is a demand for low power consumption, the terminal is allowed to perform a sleep operation to save power consumption. For example, in a cellular network, a terminal may sleep in a DRX cycle, and in a Wi-Fi network, a terminal may sleep in a sleep cycle specified by an AP.

Taking the smart grid as an example, the current power system automation technology has undergone profound changes, and it is gradually developing from partial and single-function automation to integrated automation of the overall system, and extending from transmission network automation to distribution network automation. The distribution network refers to a power network below 110KV that receives electric energy from the transmission network or regional power plants, and distributes it locally through power distribution facilities or distributes it to various users step by step according to voltage. The main functions of the distribution network include: data acquisition and monitoring (Supervisory Control And Data Acquisition, SCADA), fault detection isolation and recovery (Fault Detection Isolation Recovery, FDIR), voltage and reactive power management (Integrated Volt-VARControl, IVVC), phase Angle measurement (phasor measurement unit, PMU), load management, etc. The realization of these functions of the distribution network is inseparable from the automation equipment - the communication between the feeder terminal unit (FTU) and the power grid control center.

Large-scale chain blackouts occur frequently around the world, causing huge losses. The North American blackout in 2003 caused an economic loss of about US$6 billion. Therefore, in order to improve the global visibility and early warning capabilities of the distribution automation in the smart grid, smart and rapid self-healing is very important. The power distribution automation system needs to monitor the FTU information of the power distribution equipment, and if there is any abnormality, it needs to be reported to the SCADA system for judgment and processing.

Since the distribution network is medium voltage, the FTU may be powered by batteries. At this time, the FTU terminals have low power consumption requirements and need to sleep. Therefore, the solution to the typical scenario shown in Figure 1 is usually:

1. FTU monitoring terminal 1 and FTU monitoring terminal 2 (s1, s2 for short) report that the line has no current and there is an open circuit fault;

2. The base station forwards the information reported by s1 and s2 to the SCADA system;

3. The SCADA system judges the fault area based on the information reported by the collected relevant sensors, and decides to disconnect the FTU execution terminal (circuit breaker 1, r1 for short) that matches s1 to minimize the fault range;

4. After receiving the network disconnection message sent by SCADA to r1, the base station first judges whether r1 is in a dormant state at this time, and if it is in a dormant state, the base station sends a wake-up message to r1;

5. When r1 is woken up, the base station will forward r1 the network disconnection decision information sent by SCADA, and r1 will perform corresponding disconnection operations according to the network disconnection decision information.

In the execution of this scheme, if the execution devices such as r1 are in a dormant state, the base station needs to wait for the decision message of the SCADA system to disconnect the network, and then wake up the corresponding execution device according to the decision message before forwarding the SCADA to the execution device. Execution message for the device. The overall execution delay is longer.

The technical solutions of the embodiments of the present invention will be described in further detail below with reference to the drawings and embodiments.

Detailed ways

The following uses Figure 2 and Figure 3 as an example to describe the fault location and isolation method provided by the embodiment of the present invention in detail. Figure 2 is a fault location and isolation method in the low-power distribution communication network system provided by the embodiment of the present invention A schematic diagram of the method; FIG. 3 is a flowchart of a fault location and isolation method provided by an embodiment of the present invention. As shown in Figure 2, the base station or AP receives the alarm messages sent by the FTU execution devices r1 and r2, and at the same time reports to the smart grid server, searches for the FTU execution device that matches the FTU monitoring device in advance, so that the FTU execution device can be monitored. Wake up in advance, thereby reducing the execution delay of execution devices with low power consumption requirements, and improving the execution efficiency of fault emergency isolation.

The specific fault location and isolation method is shown in Figure 3, including the following steps:

Step 301, receiving alarm information sent by the monitoring equipment, the alarm information including fault information and information of the monitoring equipment that generated the alarm information;

Specifically, the FTU monitoring equipment is installed in the feeder line to collect and monitor the operation of the power distribution system and various parameters, such as: feeder voltage, current, active power, reactive power, power factors, device states of various switches, etc. In the system shown in Figure 2, when the FTU monitoring devices s1 and s2 detect the occurrence of a fault, they send alarm information in the form of wireless communication. The alarm information may include fault information or the group to which the FTU monitoring device belongs. No. The base station or AP receives the alarm information sent by s1 and s2, and can search for the FTU execution device corresponding to the group number according to the group number.

Step 302, searching for an execution device matching the monitoring device according to the alarm information, and sending the alarm information to the server;

Specifically, the logical correspondence between the FTU monitoring device and the FTU execution device is preset in the base station or the AP, for example, s1 corresponds to r1, and s2 corresponds to r2. The base station or AP searches for the FTU execution device corresponding to the FTU monitoring device that receives the alarm message according to the above logical correspondence.

At the same time, the base station or AP forwards the alarm information of s1 and s2 to the smart grid server.

Step 303, sending a wake-up message to the execution device, so that the execution device remains in the wake-up state within a first time after receiving the wake-up message;

Specifically, the base station or the AP sends serial data to the FTU execution devices r1 and r2. When the FTU execution device is in the wake-up state, it will respond to the serial data and reply the response data to the base station or AP; when the FTU execution device is in the sleep state, it will not send a response. The base station or the AP judges whether the FTU execution device is in a dormant state according to whether the response data is received. For example, the base station only receives the response data sent by r2 to identify that r1 is in a dormant state and r2 is in an awake state.

After recognizing that the FTU execution device r1 is in the sleep state, the base station or the AP sends a wake-up message to r1 to wake up the FTU execution device r1 to be in the wake-up state, and the wake-up state lasts for the first time. The first time refers to the allowable time for the smart grid server to generate decision information in response to the alarm after the base station or AP forwards the alarm information to the smart grid server and send it to the base station or AP.

After recognizing that the FTU execution device r2 is in the wake-up state, the base station or the AP sends r2 a wake-up message for updating the wake-up time of the execution device, so that r2 continues to stay in the wake-up state within the first time after receiving the wake-up message. In order to prevent r2 from going to sleep before receiving the decision information when there is decision information.

Further, the wake-up message can be sent in an explicit or implicit manner. The explicit sending refers to directly sending the wake-up message to the FTU execution device; the implicit sending refers to sending the wake-up message to the FTU execution device by carrying the wake-up information in the broadcast or multicast message.

Step 304: Receive the decision information generated by the server within the first time according to the alarm information, and send it to the execution device, so that the execution device executes the action corresponding to the decision information.

Specifically, the smart grid server generates decision information in the first time according to the received alarm message and sends it to the base station. If the smart grid server decides to send r1 a decision message to perform a disconnection action, then the base station receives the decision message sent by the smart grid and forwards it directly to r1 that has been awakened, so that r1 performs the corresponding disconnection action, thereby realizing the Fault isolation on the line.

If the smart grid server decides to send r2 a decision message to perform a disconnection action, then the base station receives the decision message sent by the smart grid and directly forwards it to r2 in the wake-up state to perform the corresponding disconnection action, thereby realizing the disconnection on the line fault isolation.

Preferably, the base station or AP has a timer, so it can be judged according to the timer whether the decision information of the smart grid server is received within the first time after the alarm information is forwarded to the smart grid server. For the execution device that has not received the decision information from the smart grid server after the first time judged by the timer, the base station or the AP sends a dormancy message to the execution device, so that the execution device enters a dormancy state.

In addition, the above-mentioned putting the execution device into the dormant state can also be executed by the FTU execution devices r1 and r2 by themselves. The FTU execution devices r1 and r2 each have a timer. When r1 and/or r2 have not received the decision information of the smart grid server within the first time after receiving the wake-up message, r1 and/or r2 automatically enter the dormant state.

The fault location and isolation method provided by the embodiment of the present invention is based on the logical correspondence between the FTU monitoring terminal and the FTU execution terminal in the smart grid, and realizes that the corresponding FTU execution equipment is advanced according to the alarm message of the FTU monitoring terminal. Wake up, thereby solving the problem that the FTU execution device needs to wait for the decision message of the smart grid server to wake up before accepting the decision message execution command, and reducing the execution delay of the FTU execution device with low power consumption requirements.

The above fault location and isolation method provided by the present invention is also applicable to the case where one FTU monitoring device corresponds to multiple FTU execution devices. In one example, the FTU monitoring devices include s1, s2, and s3, wherein the execution devices corresponding to s1 include r11, r12, and r13, the execution devices corresponding to s2 include r21, r22, and r23, and the execution devices corresponding to s3 include r31, r32, r33. The monitoring devices s1, s2, and s3 all report an alarm message, and the base station or AP sends a wake-up message to all execution devices, and forwards the alarm message to the smart grid server. The smart grid server generates decision information for r11 and r32, and requests to execute actions corresponding to the decision information. The base station or AP forwards the decision information to r11 and r32 correspondingly, and sends a message to enter the dormant state to other execution devices after the first time after sending the wake-up message.

Further, the detection device further includes: a storage unit 440, configured to store the logical correspondence between the monitoring device and the execution device.

Further, the detection device further includes: an identification unit 450, configured to identify whether the execution device is in a dormant state.

Find the FTU execution device that matches the FTU monitoring device for the logical correspondence between them. The identifying unit 450 sends serial data to the FTU executing device found by the searching unit 420 through the sending unit 430, and identifies whether the FTU executing device is in sleep according to whether the receiving unit 410 receives the response data from the FTU device. When the identification unit 450 recognizes that the FTU execution device is in the dormant state, the sending unit 430 sends a wake-up message to the FTU execution device, so that the FTU execution device enters the wake-up state, and the wake-up state lasts for the first time. The first time refers to the allowed time for the base station or AP to forward the alarm information to the smart grid server if the smart grid server decides to respond to the alarm to generate decision information and send it to the base station or AP; when the identification unit 450 recognizes that the FTU execution device is in the wake-up state At this time, the sending unit 430 sends a wake-up message for updating the wake-up time of the FTU execution device to the FTU execution device, so that the FTU execution device continues to stay in the wake-up state within the first time after receiving the wake-up message. The receiving unit 410 receives the decision information sent by the smart grid server, and the sending unit 430 forwards the received decision information to the FTU execution device in the wake-up state to perform corresponding actions, so as to realize rapid isolation of faults.
