Power Systems State Estimation Acceleration on the Basis of the Synchronized Phasor Measurements in the Power System Steady State Control Tasks

Abstract

In most of the world's energy systems, in recent years there has been a widespread introduction of synchronized phasor measurements (SPM). They allow both to obtain measurements of the traditional parameters of the established mode (voltage $V$ and current $I$ modules, active $P$ and reactive $Q$ power) with a time stamp, and to measure new parameters, namely, the phase angles of voltage δ and current $\varphi$. The focus on SPM in dispatching and emergency control systems is due to a number of factors, the most important of which is a sharp increase in the accuracy of measurements, since measurement non-synchronism is the main source of error in telemetry (TM).
