【摘要】：針對現(xiàn)有的智能變電站仿真試驗(yàn)系統(tǒng)無法良好應(yīng)用于變電站現(xiàn)場等問題,提出了一種基于無線數(shù)據(jù)通信的智能站二次設(shè)備集成測試方案,并研發(fā)了系統(tǒng)軟硬件。該系統(tǒng)采用電磁暫態(tài)計(jì)算獲取整站正常運(yùn)行及間隔典型故障的電流電壓值,通過專用的亞毫秒級高速同步無線數(shù)據(jù)通道將試驗(yàn)數(shù)據(jù)發(fā)送到各被測間隔,并開發(fā)分布式數(shù)據(jù)終端實(shí)現(xiàn)仿真測試系統(tǒng)與變電站二次系統(tǒng)的無縫連接,完成二次系統(tǒng)不同范圍、不同功能的重點(diǎn)測試。通過實(shí)際變電站的模型搭建及故障仿真測試,驗(yàn)證了該測試系統(tǒng)的有效性。
[Abstract]:Aiming at the problem that the existing intelligent substation simulation test system can not be applied to substation field well, this paper presents a scheme of intelligent station secondary equipment integrated testing based on wireless data communication, and develops the software and hardware of the system. The current and voltage values of normal operation and typical faults of the whole station are obtained by electromagnetic transient calculation, and the test data are transmitted to each measured interval through a special high-speed synchronous wireless data channel of sub-millisecond level. The distributed data terminal is developed to realize the seamless connection between the simulation test system and the secondary system of substation, and to complete the key test of different range and function of the secondary system. The validity of the test system is verified by the actual substation model building and fault simulation test.
