发电厂电气系统中谐波的问题与控制措施

The Problem of Harmonic in Power Plant Electrical System and Control Measures

无可否认,电力已经成为我们生活中不可或缺的资源,没有电力,生活将变得难以想象。然而,发电质量不高是当前发电厂面临的主要难题,电网谐波导致供电质量下降,从而影响我们的工作和生活。电源质量低下导致谐波产生,用电设备和输配电系统也会产生谐波,谐波的治理对于社会发展有着明显的促进作用。除了需要预防谐波,还需要准备补救措施,使谐波对供电质量的影响降到最低。该文在论述谐波问题的基础上提出了解决问题的可行性方案。

There is no denying the fact that electricity has become an indispensable resource in our life. Without electricity, life will become unimaginable. However, the power quality is not high is the main problem of the current power plant, power grid harmonics lead to power supply quality down, thereby affecting our work and life. The power quality is low to the harmonic generation, the power equipment and power transmission and distribution system also produce harmonic, and the harmonic of the management has a significant effect on the social development. In addition to the need to prevent the harmonic, it is also required to prepare remedial measures, so that the impact of harmonics on the power supply quality is reduced to a minimum. On the basis of discussing the problem of harmonic, this paper puts forward a feasible plan to solve the problem.
