Method of acquiring basic evaluation data of synchronous generator excitation system performance

Abstract

The invention relates to a method of acquiring basic evaluation data of synchronous generator excitation system performance. The method of acquiring basic evaluation data of synchronous generator excitation system performance includes the steps: determining the basic evaluation factors of synchronous generator excitation system performance; determining the acquisition channel of the basic evaluation data corresponding to the basic evaluation factors; and finally acquiring the basic evaluation data through the acquisition channel. The determined basic evaluation factors not only include a sensitive basic evaluation factor, but also include an insensitive basic evaluation factor, so that the comprehensiveness of the evaluation data is improved; and the determined acquisition channel includes field tests, simulation calculating of excitation system, nameplate technology parameter data and power grid operation record data, and performs adaptive selection for different basic evaluation factors, so that accuracy of the evaluation data is improved. The method of acquiring basic evaluation data of synchronous generator excitation system performance can acquire comprehensive and accurate evaluation data so as to provide basis for graded evaluation of excitation system performance.

Description

technical field [0001] The invention relates to a method for acquiring basic evaluation data of the performance of an excitation system of a synchronous generator. Background technique [0002] The increasing scale of the power grid and the massive grid-connection of fluctuating energy sources such as wind power have brought more disturbances to the power system. The problem of safe and stable operation of the power grid has become increasingly prominent. More attention has been paid to the regulation of the excitation system. The importance of comprehensive and accurate performance evaluation and its application to guide field work and power system scheduling has attracted more and more attention. The synchronous generator excitation system points to the synchronous generator to provide excitation power and its ancillary equipment. The excitation regulator controls the output of the excitation power unit according to the input signal and adjustment criteria, and realizes t...
