Ensuring the quality of electric power for agricultural consumers with power supply from a solar power plant in parallel with a centralized mains

The article discusses the issues of operation of a grid solar power plant, the requirements for the quality of electricity from the consumer when supplying power from the operating station and the factors affecting the distortion of the output parameters of the inverter. The constructed experimental station is described, which makes it possible to estimate the output values of voltage and frequency. The brands and characteristics of the main components used in the construction are presented. On the basis of real data on the deviation of voltage and frequency at the output of the grid power plant, the authors formulated the requirements for connecting and operating the station in parallel with the centralized network. Also, with the help of the constructed station, a study of the impact of emergency and post-emergency modes on the quality of electricity from a solar power plant was carried out. As a result of the experiment, conclusions were drawn about the short-term desynchronization of the station and the centralized network when the short circuit was removed.
