Black-start assistant decision-making system based on DTS

Abstract

The application belongs to the computer calculation field of an electrical power system, and discloses a power grid black-start assistant decision-making system. The black-start assistant decision-making system includes three parts of a pattern platform, a database, and an algorithm analysis library. The pattern platform is formed by a picture browser of a smart power grid dispatching technical support system and a self-developed window. The database stores each element parameter in the electrical power system and analysis results, which is convenient for user modification and checkup. The algorithm analysis library includes a numerical analysis algorithm and an optimization algorithm used in a black-start process. The algorithm analysis library is a technology core of the whole system. The black-start assistant decision-making system based on the DTS is characterized in that the system adopts a modular hierarchical structure including a data layer, an application layer, an application support layer, an interface layer and a user layer. According to the invention, the black-start assistance decision-making system and the DTS based on a D5000 smart power grid dispatching technical support system are integrated together, share a real-time power grid database, a data communication platform, and power grid pictures.

Description

technical field [0001] This application belongs to the field of power system computer calculation, and is an auxiliary decision-making software for power grid black start. Background technique [0002] Black start refers to the process of gradually restoring the normal operation of the power system by using the self-starting unit in the system or the power supply outside the system when the power system is completely shut down. Since the 1960s, many experts and scholars at home and abroad have devoted themselves to the theory and method of reducing the probability and scope of power accidents, and have achieved remarkable results. The problem of how to recover as soon as possible after an accident in the power system is the black start problem. was relatively ignored. The research on the restoration of the power system blackout accident began in the middle of the 1980s, and the restoration of the blackout area can be divided into two types: the restoration of the partial bl...

AI Technical Summary

Problems solved by technology

Missing these intervals will delay system recovery

[0031] 6) Self-excitation problem in the early stage of black start

[0033] 7) Closing overvoltage problem of no-load line

It is impossible to closely track the current operating power system, so it is impossible to quickly calculate the black start plan for the current operating system online

[0046] 2) In the black start plan, the amount of system recovery calculation is huge, and the calculation time is often counted in several hours, which cannot provide auxiliary decision-making for power grid dispatching operation online

[0047] 3) It is impossible to perform real-time training simulation on the formed black start plan

[0048] 4) Unable to carry out plan deduction on DTS
