METHOD FOR DETERMINATION OF POWER GRID FREQUENCY STATIONARY VALUE MEASURING THE TRANSIENT PARAMETERS OF PROCESS

摘要

This invention relates to electrical power engineering and in particular, to methods for management of a power system. Its goal is to speed up the data acquisition process. The method proposed, in accordance with which at successive time moments the frequency f1 and f2 are measured and its alteration speed f'1 and f'2 and frequency stationery value fstac, which is calculated by the formula: fstac. = f1 + (f2 - f1)/( f'1 - f'2) f'1. Fig. 3 shows one of possible block diagrams for realization of the method.
