Influence of solar power plants on 0.4 kV consumers

Abstract

The results of the study of the influence of active power produced by solar power plants (SPP) on voltage 0.4 kV tires of consumers are presented. It is proved that in local electrical systems: there are possible modes when the voltage on the 0.4 kV bus of consumers can be outside the normalized values; almost without limiting the generation of active power SEP and regulating reactive power SPP is the ability to regulate the voltage on 0.4 kV tires consumers, to prevent excess normalized voltage deviations. This will reduce the use of voltage transformers and switching devices for static capacitors.
