摘要
电力系统中电磁环境复杂,存在众多的电磁干扰源和运行于变电站、发电厂等场所的易受干扰设备,随着电力系统的不断发展,电网容量增大,电压等级提高,以计算机、微电子技术为基础的自动化设备趋于集成化、智能化以及功能一体化,这使电力系统中的电磁兼容性问题更加突出。文章主要介绍了电力系统中所涉及的电磁兼容性问题及研究进展情况。
The electric-magnetic environment is very complicated in electric power system; there exists so many powerful interfering source and sensitive equipment that runs in substation, power plant, etc. As the development of electric power system, the capability of power network will be larger, the voltage level of transmit will more high and the automatic based on the technology of computer and micro-electronic will be more integrated, intellectualized, and multi-functional, which makes the EMC issues in the electric power system be worse. This paper Mainly introduces the EMC problem involved in electric power system, and also introduces the research development progress in electric power system now.
