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 E, 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 Eand value of the parameter are set so that conditions E?set E=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 Evalues is changed up to the preset value, where ?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
