| 摘要: |
| 以西北—华中直流联网工程(灵宝工程)为例,给出了基于实时数字仿真器RTDS(RealTimeDigitalSimulator)的高压直流输电(HVDC)控制保护设备闭环测试方法、系统构成。针对RTDS中缺乏工程设计的滤波器,采用等调谐锐度法建立了等效滤波器的模型。为使闭环系统有所参照及RTDS可脱离控制保护设备单独运行,设计了一内部控制系统。所建模型已用于灵宝工程控制保护设备的实验室测试中,设计规范、内部控制和外部装置控制间的结果对照表明所建系统模型正确。所使用方法及经验可推广到今后HVDC控制保护设备的测试中。 |

| Abstract: |
| With Lingbao Project as an example,a test system for HVDC control and protection devices based on RTDS(Real Time Digital Simulator) is introduced.Special filter model,which is absent in RTDS model library,is designed according to equal-tune-sharpness.To make RTDS operating independent of control and protection devices,an internal control system is designed.Tests in lab show that the designed system is correct.The introduced method and experiences can be used to other closed loop system test of HVDC control and protection devices. |
