电能质量问题及改进措施

Problem of Electric Power Energy Quality and Its Improving Measures

在电力系统中,供电的质量指标、电网运行的安全可靠性和经济性是最根本的问题。而电网中存在谐波、无功、电压闪变等问题,严重影响电能质量,危害电力设备。文章从电能质量问题的分类、产生原因及改善电能质量问题的措施等几个方面进行了阐述。

In electric power system, the essential problem is the quality guideline of power supply, the security and reliability of the power grid operation, but some problems such as harmonic wave, reactive power and voltage flicker effect are seriously influenced the power quality, and endangered power equipment. The paper makes an analysis from several aspects, such as the problem classification of electric power energy quality, its rcason and the improving measures.
