Distribution network automation master station batch presetting communication method

Abstract

The invention discloses a distribution network automation master station batch presetting communication method. The method adopts the idea of dynamic queue control; and compared with a direct batch presetting method in the prior art, the method can automatically and orderly preset terminal devices in batches, solves the problem of congestion of a communication channel and reduces server pressure.The method can be compatible with the problem of different preset response time of different devices to ensure queue stability, and can automatically traverse a preset device list to ensure normal communication and effectively prevent packet loss. In a master station system, the method carries out simulation test on a lot of virtual terminals; and in the simulation presetting test process, the method can greatly reduce system CPU occupancy rate, thereby improving system response speed.

Description

technical field [0001] The invention belongs to the technical field of distribution automation, and in particular relates to a batch preset communication method for a master station of distribution network automation. Background technique [0002] The power industry is the basic industry of the national economy, and stable power supply plays a key role in the development of the national economy. The existing power grid construction is complicated and huge, with a long time span, and various new and old equipment are mixed in it. Many grid structures are no longer suitable for modern power supply needs. However, the cost of power grid transformation is huge, and it will not happen overnight. [0003] In the existing power grid, if natural disasters and other unknown damages and other accidents occur, the normal operation of the power grid will be seriously threatened, and even the line will be interrupted. However, it takes a long time to find the damage point manually. It w...

Problems solved by technology

[0007] Presetting, that is, sending a preset signal to the distribution terminal through the master station of distribution automation, checking the communication, and the common means of FTU logic circuit is normal. When the traditional distribution automation master station performs batch preset for a large number of distribution terminals, usually A large number of power distribution terminals issue preset commands at the same time, and the power distribution terminals return orders almost at the same time. This operation will cause serious congestion in the communication channel of the entire distribution network automation system, and put a huge pressure on the server. It will not only cause the loss of normal equipment signals, The failure of normal terminal presetting may also affect other work of the distribution automation master station, seriously affecting the stable operation of the power grid
