浅议电力系统电压与无功补偿

A simple discussion on pressure and reactive compensation of power system

随着经济发展和人民生活水平的提高,用户对电力的需求日趋增长,对电能质量也提出了更高的要求。电压质量对电网的安全与经济运行,对保证用户安全生产和产品质量以及电气设备的安全与寿命有着重要的影响。通过对电压与无功功率的关系进行分析可知,进行无功功率补偿对提高电压水平有着至关重要的作用。此外,合理使用补偿装置及科学选定补偿容量,会在供电质量范围内合理的提高电压,产生节能效益,确保电能质量最佳。

With the development of our national economy and the rise of people＇s living level, the power needed for consumers increases progressively, and the higher requirement for power quality is also put forward. The voltage quality has great influence on the safety and economical operation of the power net, the product quality as well as the safety and service life of the electric equipments. Through the analysis of the relationship between voltage and reactive power, it can be known that, reactive power compensation plays a crucial role in enhancing the voltage level. It also indicate that, With the rational use of reactive power compensation and the scientific selection of compensation capacity, the voltage is reasonably enhanced within the quality range of power supply, which can obtain energy saving benefit and insure the optimal power quality as well.
