摘要
在介绍 H400 换流阀控制保护原理的基础上,描述了直流控制保护系统与换流阀控制保护接口的设计和实现方法,尤其是直流极控制系统与阀基电子设备间的信号类型、信号实现方式,包括光控制信号、电气开关量信号等。宁东—山东直流输电工程中应用实践表明了换流阀控制保护接口技术的有效性和可靠性。
Based on the control and protection scheme of H400 converter valve,the design and realization of interface between DC control protection system and the control protection of converter valve are illustrated in detail.The type and function of signals between converter control and protection(CCP) and valve vase electronics(VBE) are demonstrated,including optical control signals,electrical I/O signals and so on.The effectiveness and reliability of the control protection interface technology of converter valve are proved by the application in the Ningdong-Shandong HVDC transmission project.
