随着智能电网的全面发展,电力公司和他们的用户都开始从事智能电网技术的研究项目,这些项目的资金投入高达数百万美元。现已有包括电力科学研究院(EPRI)在内的数十个科研机构对数以百计的以智能电网为主题的项目进行研究。对电力行业来说,电能质量(PQ)一直都是(现在仍是)具有重要意义的主要课题之一。可靠性和兼容性是终端设备对电力性能的需求,在某种程度上,高质量电源的频率分布在50Hz或60Hz~3kHz之间。在当今不断变化的环境下,
With the all-encompassing development of smart grids, utility companies and their customers are starting research projects in smart grid technology that spend as much as millions of dollars. Dozens of research institutes, including the Electric Power Research Institute (EPRI), now study hundreds of smart grid-themed projects. For the power industry, power quality (PQ) has been (and still is) one of the major topics of great significance. Reliability and compatibility are the requirements of terminal equipment for power performance. To some extent, the frequency of high quality power supplies is distributed between 50Hz and 60Hz ~ 3kHz. In today’s ever-changing environment,
