技术领域technical field
本实用新型涉及馈线自动化领域，具体涉及一种无须联网的馈线自动化测试系统。The utility model relates to the field of feeder automation, in particular to a feeder automation test system without networking.
背景技术Background technique
馈线自动化主要依据安装在配电线路上的配电终端采集的故障信号，结合配电线路的网络拓扑以及故障前的运行状态，自动实现故障区段的定位，隔离，非故障区域的供电恢复。馈线自动化对提高供电可靠性与供电质量有非常重要的作用。Feeder automation is mainly based on the fault signal collected by the distribution terminal installed on the distribution line, combined with the network topology of the distribution line and the operating status before the fault, automatically realizes the location and isolation of the faulty section, and restores the power supply in the non-faulty area. Feeder automation plays a very important role in improving the reliability and quality of power supply.
配电网络中设有很多控制开关，各个控制开关都配置有用于监控其工作的监控终端，在对配电网络的馈线进行自动化现场测试时，需要根据配电网络的拓扑结构，在被测线路的所有控制开关的监控终端上注入测试电流，并在故障点上游注入故障电流，在故障点下游不注入电流或者注入小电流，同时需要配合出口断路器保护动作后的电压变化过程，跳闸前需要在电流端子上加上电压，跳闸后需要及时去掉电压。由于电气数据同时性的特点，在不联网的前提下，测试时往往需要很多的人员在线路的不同区域的监控终端处紧密配合，才能完成一个测试用例的测试，要对一条包含多个开关的线路进行完整的测试，需要耗费大量的人力与时间。There are many control switches in the power distribution network, and each control switch is equipped with a monitoring terminal for monitoring its work. When performing an automated on-site test on the feeder of the power distribution network, it is necessary to perform a test on the tested line according to the topology of the power distribution network. The test current is injected into the monitoring terminals of all control switches, and the fault current is injected upstream of the fault point. No current or small current is injected downstream of the fault point. At the same time, it needs to cooperate with the voltage change process after the outlet circuit breaker protection action. Add voltage to the current terminal, and remove the voltage in time after tripping. Due to the characteristics of electrical data simultaneity, under the premise of not being connected to the Internet, it often requires a lot of personnel to cooperate closely at the monitoring terminals in different areas of the line to complete the test of a test case. A complete test of the line requires a lot of manpower and time.
