基于STATCOM矿井电力系统无功补偿技术

摘要

矿井电气设备是我国采矿企业使用范围广、耗能大的重要大功率设备之一，在工作过程中它需要频繁的启动、运行和停机，对煤矿电力系统的无功冲击比较严重。本文在分析无功补偿技术原理的基础上，针对矿井电力系统特点开展无功补偿技术的研究，设计STATCOM矿井无功补偿系统及其调节单元，对于提高矿井电能质量和保证井下高效、安全生产具有重要的意义。%Mine electrical equipment, the use range of mining enterprises in our country, one of the important power equip-ment of large energy consumption, in the process of work it requires frequent start-up, operation and stop to the coal mine power system reactive power impact are more serious. In this paper, on the basis of analyzing the principle of reactive compensation technology, according to the characteristics of the mine power system for the research of reactive power compensation technol-ogy, design of STATCOM mine reactive compensation system and its control unit, power quality and guarantee for improving mine down hole efifciency and safety in production is of great importance.
