Features of operation of the grid connected photovoltaic power station with a capacity of 10 kW

Abstract

Photovoltaic power station (PPS) operating function (without redundancy) with a nominal capacity of 10 kW connected to the low voltage electrical network established by "Zhejiang Chint Electrics Co Ltd" (PRC) under Tashkent conditions is defined. Operation parameters and characteristics of the PPS and parameters at the output of the network inverter are given. The deviations of voltage of each phase from the standard nominal voltage at the point of electric network transmission are studied. The analysis of the results of the evaluation of the power generation of the PPS for the conditions of clear weather and clear cloudiness was carried out. According to the monitoring data for the winter period is 2211,5 kW·h. The problems of PPS connected to the low-voltage network, connected to the loss of electric power with the account of influence of external factors and reliability of stable voltage and frequency in a permissible range are revealed.
