一种电网广域保护与控制系统
摘要：
本发明公开了一种电力系统广域保护与控制系统，其包含一个保护控制主站，若干保护控制子站、就地采集控制设备及通讯网关设备。所述的保护控制主站接收所有保护控制子站上送的信息，并对保护控制子站下发控制命令；所述的保护控制子站通过就地采集控制设备进行模拟量、开关量的采集，并发送保护控制主站所需的本站信息,接收保护控制主站的控制命令；所述的保护控制子站还与广域范围内的其他保护控制子站交换信息，从而实现广域范围内保护与控制系统的信息共享，使安全自动控制系统与保护系统能够自适应协调控制。
摘要（英）：

The invention discloses a power system wide area protection and control system which comprises a protection control main station, a plurality of protection control substations, a local collection control device and a communication gateway device. The protection control main station receives information uploaded by the protection control substation and transmits a control command to the protection control substation. The protection control substation conducts collection of analog quantity and on-off quantity through the local collection control device, transmits home station information required by the protection control main station and receives the control command of the protection control main station. The protection control substation exchanges information with other protection control substations in the wide area range to achieve information share between the protection and control system in the wide area range, and the safe automatic control system and the protection system can achieve self-adaptation coordination control.
