IEEE PC37.252 PDF
This guide describes the application philosophy, limitations, and testing methods for the automatic voltage control (AVC) system of the regional power grid. This guide applies to the testing for reactive-power-control-based AVC systems in the regional grid.
The purpose of this guide is to describe the methods of testing the functions and technical performance of the regional AVC systems, with a view to finding the potential defects of AVC systems and improving the operational performance of AVC systems.
