Black-start comprehensive verification system of power system and method of black-start comprehensive verification system

Abstract

The invention discloses a black-start comprehensive verification system of a power system and a method of the black-start comprehensive verification system. With the black-start comprehensive verification system, various technological verification problems of black start are solved on the same system platform, verification calculation results of overvoltage verification of a black-start scheme of the power system, voltage frequency verification during starting of an auxiliary machine and self-excitation verification are output by verification calculation of all contents such as overvoltage verification of the given black-start scheme, the voltage frequency verification during starting of the auxiliary machine and the self-excitation verification, and thus, whether the set black-start scheme of the power system is appropriate or not can be effectively determined; and meanwhile, by a friendly pattered human-computer interaction interface, the burdens of system model building and data input / output processing are reduced, result analysis and verification conclusion judgment are automatically carried out, the verification complexity and the working burden of the black-start scheme are greatly reduced, and an effective auxiliary tool is provided for making and revision of the black-start scheme.

Description

technical field [0001] The invention relates to the technical field of power system black start, in particular to a power system black start comprehensive checking system and a method thereof. Background technique [0002] Black start is the process of gradually expanding the power supply range of the system through the start of units with self-starting capability in the system without relying on the help of other systems after a power outage of the entire system to drive the units without self-starting capability, and finally realizing the recovery of the entire system. [0003] In the process of black start, there are some technical problems that cannot be ignored, such as the operating overvoltage generated by the no-load closing operation, the influence of the input of the electric motor in the power plant load to the generator voltage and frequency on the generator voltage and frequency, and the Possible self-excitation problems. The existence of these problems may lea...

Problems solved by technology

This verification method requires the operator to carry out system modeling and input and output data processing for different software systems. At the same time, since the verification conclusion cannot be given intuitively, the result analysis and conclusion can be completed through the operator's own manual calculation and data comparison. determination

This makes the black start verification a very complicated technical work, with a very heavy workload and high requirements for operating personnel. It is difficult to meet the requirements of rapid formulation and timely revision of the black start plan, and cannot meet the needs of system operation.
