METHOD FOR PARAMETERS SETTING FOR EXCITING REGULATOR OF ASYNCHRONOUS GENERATOR

摘要

FIELD: electricity.;SUBSTANCE: parameters of exciting regulator are set against deviation of setup of one of its output signals; initial value of parameters optimisation criterion for regulator is E₀, a new value of parameters optimisation criterion for the regulator is calculated in compliance with formula; setup of the regulated output signal is changed by constant value for fixed time; scale and duration of transient process for the generator output signal is measured against the specified changed setup, new value of parameters optimisation criterion for the regulator E is calculated in compliance with formula and value E₀ and value of the parameter are set so that conditions EE₀ is met or the following conditions are met: E≥E₀ and (E-E₀)/cβ_i set E₀=E and the parameter is not changed. Otherwise the parameter is set to initial value. The above operations are repeated for other parameters subjected to regulation till average rate of E₀ values is changed up to the preset value, where β_i is a random value distributed evenly within the range [0.1], c is a positive permanent value that determines rate of optimisation for the regulator parameters.;EFFECT: automatic optimisation of parameters for exciting regulator of synchronous generator at stage of its input into operation without destabilising influence on the power system and loss of its stability.;1 dwg
