The invention discloses a method for automatically restoring power supply based on a power distribution Internet of Things gateway, which includes the following steps: S1. The power distribution Internet of Things gateway regularly obtains secondary equipment in the medium-voltage system of the power distribution room and the low-voltage system of the power distribution room through a communication method The collected telemetry data and remote signaling data are saved; S2. If the variation of any telemetry data received by the power distribution Internet of Things gateway exceeds the preset value or the telemetry data changes, it will be compared with the previously received telemetry data , remote signaling data for comparison, and combined with the topological relationship between the associated primary equipment for fault analysis; S3, diagnosis and determination of the fault area; S4, the power distribution IoT gateway sequentially sends remote control signals to the corresponding protection measurement and control devices, frame open circuit switch, molded case circuit breaker, restore power supply in non-faulty areas and report action information. The present invention improves power supply reliability, shortens power outage time, and saves operation and maintenance costs without adding electrical energy hardware collection equipment to the power distribution room.
Description
technical field [0001] The invention belongs to the technical field of electric power system automatic control, and in particular relates to a method for automatically restoring power supply based on a power distribution Internet of Things gateway. Background technique [0002] With the rapid development of the economy and power industry, there are many substations and power distribution rooms of various voltage levels. While bringing convenience to people's work, production and life, it also puts forward more requirements for the reliability of power supply of substations and distribution stations. High requirements, in the substation integrated automation system, the automatic input device of the backup power supply is mainly used to restore the power supply quickly; in the distribution automation system, the main distribution line mainly adopts the centralized control of the master station or the distributed self-healing protection control to restore the power supply , th...
