Determination of The Instantaneous Electrical Operating Parameters With an Increased Sampling Rate

Abstract

The paper presents the algorithm for the rapid assessment of electrical operating parameters with a delay of less than one industrial frequency period. The method for setting the basic frequency when representing a signal by the Euler method was studied, as well as two algorithms for determining the synchronous frequency in a three-phase network based on voltage signals were developed, with determining the scope of the algorithm. The computational model of the transient in the electrodynamic simulator of STC UPS, JSC, and the steady-state data in a 500 kV grid were chosen for the tests. The delay values in determining the operating parameters by the algorithm are obtained for each data type.
