电网运行RTDS分析的可行性及方式探讨

南方电网仿真实验室作为中国南方电网有限责任公司的重点实验室,拥有国际上最先进和最大规模的实时数字仿真装置(RTDS)资源,如何发挥资源优势,更好地为南方电网交直流并联运行系统提供仿真分析,一直倍受关注。鉴此,对RTDS应用于南方电网运行分析的可行性及方式进行探讨,指出RTDS具有与实际控制保护装置闭环连接进行试验的独特优势,但由于仿真规模有限,需要进行电网等值处理,电网仿真分析的时效性及适应性受限。在此基础上,提出了RTDS为南方电网运行分析提供支持的工作设想。

Research on the Feasibility and Mode of RTDS Analysis of Power System Operation

China Southern Power Grid Simula-tion Laboratory, as the key laboratory of China Southern Power Grid Co. Ltd, has the most ad-vanced and larg-est-scale RTDS simulation resources worldwide. It is the focus of attention how to use the ad-vantage of these simulation resources to provide much better simulation analysis for AC-DC parallel operating system of China Southern Power Grid (CSG). In this paper, the feasibility and mode of RTDS analysis on CSG are analyzed, and it is pointed out that RTDS has the unique advantage of connecting with ac-tual control and pro-tection devices to complete the closed-loop experi-ments, but it is lim-ited by the size of model and the re-quirement of equivate power network so much that it lacks timeli-ness and adaptability of power system simulation. Fur-thermore, a plan of RTDS works in the laboratory for CSG operation analysis is proposed.
