VOLTAGE REGULATION OF SOLAR POWER PLANTS AUTONOMOUS INVERTERS
Description
In agricultural production, the direction of introduction of renewable energy for power consumers remote from the external electrical network is relevant. Here, prospects are revealed in front of the solar PV stations. One of the main functional units of solar power is inverters that convert the DC voltage of the solar panels into alternating current. The article describes the advantages and disadvantages of the main methods of voltage regulation of the autonomous inverters of solar photovoltaic power plants. We have proposed new structural designs of autonomous voltage inverters, described their advantages, features of design and operation for voltage stabilization. We suggest stand-alone inverters designed using high frequency link, which will significantly improve mass and dimensions parameters of the converter. Due to the use of single-phase transformer with a rotating magnetic field in stand-alone inverters, we improve the efficiency of the converter and the reliability of the work. Patents of the Russian Federation confirmed the novelty of technical solutions of the considered schemes of autonomous voltage inverters. Structural schematics of the voltage regulators considered in the article, as well as features of their work, will allow to increase efficiency of preliminary works on development of autonomous voltage inverters with improved operational and technical characteristics for solar photovoltaic power plants
