Експериментально отримано результати вимірювання показників якості електрое-нергії. Проведено аналіз основних показників якості електроенергії, яка генерується сонячною елек-тростанцією Ізмаїльського енерговузла і подається в енергосистему. Проведено порівняльний аналіз допустимих значень коефіцієнтів спотворення синусоїдальності кривої напруги і коефіцієнтів n-ой гармонійної складової напруги з експериментальними.
The generation of electricity with the help of solar power plants has a great potential for de-velopment in Ukraine. The analysis of the main power quality indicators generated by the solar power sta-tion of the Izmail energy unit and transmitted to the power system is carried out.
Experimentally obtained reliable results of measurement of power quality indicators. The generation of elec-tricity by alternative sources and the connection of the latter to the power system by means of current con-verters affect the quality of electricity in the network. High frequency switching inverters can create addi-tional harmonics in the network. The use of the modern PM 175 analyzer makes it possible to analyze the power quality indicators and use the results of research to develop measures to improve the efficiency of the solar power plant in the power system. A comparative analysis of the admissible values of the sinusoidal dis-tortion coefficients of the voltage curve and the coefficients of the n-th harmonic voltage component is car-ried out. As a result of the measurements daily diagrams of the sinusoidal distortion coefficients of the volt-age curve on the 110 kV buses of the Kiliya substation were obtained. The graphs of the change in the value of the coefficient of the 3rd harmonic voltage component on the 110 kV tires are obtained, taking into ac-count the work of the solar power plant, mainly clear, sunny weather. The generation of electricity by alter-native sources and the connection of the latter to the power system by means of current converters affect the quality of electricity in the network. The high switching frequency of the inverters can create additional har-monics in the systems and reduce the efficiency of the system due to the violation of the stability of the sources and the malfunctioning of the inverters. Generation of electric energy at the Kiliya solar power sta-tion of the Izmail energy unit occurs in compliance with the current standards.
