一种应用于高压直流输电控制保护系统的网络系统
摘要：
一种用于高压直流输电控制保护系统的网络系统，包括：站控制层设备，一个或多个双极控制层设备，多个极控制层设备，多个换流器控制层设备，其中，站控制层设备通过以太网分别与各双极控制层设备、极控制层设备和换流器控制层设备连接；每个双极控制层设备与下属的各极控制层设备之间以独立的实时控制网络连接；每个极控制层设备与下属的各换流器控制层设备之间以独立的实时控制网络连接；各双极控制层设备、极控制层设备以及换流器控制层设备通过现场总线与相应的就地层设备连接。采用该网络系统的高压直流输电控制保护系统系统结构简单，并保证实时性和可靠性，且可以解决海量数据的分流处理、阀组间的协调控制。
摘要（英）：

The utility model relates to a network system applied on a high-voltage direct-current transmission control protection system comprises a station control layer device, one or more bipolar control layer devices, a plurality of pole control layer devices, and a plurality of converter control layer devices, wherein the station control layer device is respectively connected with each bipolar control layer device, the pole control layer device and the converter control layer device by an Ethernet; each bipolar control layer device is respectively connected with each subordinate pole control layer device by an independent real-time control network; each pole control layer device is connected with each subordinate converter control layer device by an independent real-time control network; each bipolar control layer device, the pole control layer device and the converter control layer device are connected with the corresponding in-situ layer devices by in-situ buses. The high-voltage direct-current transmission control protection system using the network system has features of simple structure, ensured real-time property and reliability and capability of solving the split-stream treatment of mass data and coordinated control between valve groups.
