Photovoltaic power generation-based electric energy quality compensation controlling apparatus and method thereof

Abstract

The invention provides a photovoltaic power generation-based electric energy quality compensation controlling apparatus and a method thereof. The apparatus comprises a photoelectric conversion module, a central control module, a direct-current processing module, an alternating-current voltage transformer module, an H bridge inverter module and a bypass switch module; and the bypass switch module includes a plurality of insulated gate bipolar transistors in inverted series connection. Because the photovoltaic power generation-based electric energy quality compensation controlling apparatus does not employ a series transformer, the size of the apparatus is small and the cost is low. The insulated gate bipolar transistors (IGBT) are used for forming the bypass switch module, so that the connection and disconnection of the bypass switch module can be carried out rapidly. Therefore, above all, the provided apparatus has the advantages of fast processing speed, simple structure, and low generation cost.

Description

technical field [0001] The invention relates to the technical field of power quality, in particular to a power quality compensation control device and method based on photovoltaic power generation. Background technique [0002] Power quality problems will not only bring great economic losses to the industry, such as shutdowns and restarts that lead to increased production costs, damage to sensitive equipment, scrapped semi-finished products, reduced product quality, resulting in marketing difficulties and damage to the company's image and good reputation with users Business relations, etc., and will also bring harm to equipment in important power-consuming departments such as medical care, causing serious production and operation accidents. According to the research of the American Electric Power Research Institute, power quality problems lead to the loss of data, materials and productivity in the US industry every year. The loss amounted to 30 billion U.S. dollars. In Singa...
