Detection and test method and device of intelligent distributed power distribution terminal

Abstract

The invention relates to a detection and test method and device of an intelligent distributed power distribution terminal. The test method comprises the steps that an actual power distribution network system model and a central control system model are established; data and / or instructions input by a user are received, and the actual power distribution network system model is controlled to conduct simulation operation in a corresponding fault operation mode; the intelligent distributed power distribution terminal to be detected receives operation parameters of the actual power distribution network system model and sends feedback signals to the central control system model; according to performance parameters of the intelligent distributed power distribution terminal in the fault detection process, whether the intelligent distributed power distribution terminal meets the requirement or not is judged. The test device comprises a real-time digital simulator, a first switch conversion module and a second switch conversion module, and the test device forms a closed loop with the intelligent distributed power distribution terminal to be detected. Compared with the prior art, by effectively detecting the intelligent distributed power distribution terminal, the operation reliability of a power distribution network is improved, and the detection and test method and device have a very active effect on intelligent and automated construction of the power distribution network.

Description

technical field [0001] The invention relates to the detection field of intelligent distributed power distribution terminals, in particular to a detection test method and device for intelligent distributed power distribution terminals. Background technique [0002] With the rapid development of smart grid, higher requirements are put forward for the reliability of safe power supply. Aiming at the weak link in the operation of the power grid, the power production department takes effective control measures to reduce accidental power outages and narrow the scope of power outages. The main reasons affecting the power supply reliability of the distribution network in China are: planned power outages, fault power outages, temporary power outages, and power cuts. Among them, the fault power outage time can be effectively shortened by distribution automation technology. Distribution automation is an important means to improve the reliability of power supply. It can quickly isolate ...
