柔性直流输电技术极控制和阀控制设备同步化系统和方法
摘要：
本发明涉及一种柔性直流输电技术极控制和阀控制设备同步化系统和方法，其特征在于包括以下步骤：1)换流站数据采集和监控系统根据工况要求发送控制信号到换流阀直流控制保护系统；2)换流阀直流控制保护系统中的PCP控制系统根据PCP运算周期计算生成周期性的三相调制波信号，并发送到VBC控制系统和同步控制系统；3)同步控制系统根据PCP控制系统和VBC控制系统的运算周期计算得到同步控制周期，且每隔一同步控制周期对PCP控制系统和VBC控制系统做一次同步；4)VBC控制系统接收到PCP控制系统发送的三相调制波信号或同步控制系统发送的触发信号后，开始新的VBC运算周期，对接收到的三相调制波信号进行处理。本发明可以广泛应用于柔性直流输电技术领域。
摘要（英）：

The present invention relates to a flexible direct current power transmission technology pole control and protect and valve base controller synchronization system and method. The method comprises thefollowing steps that: a supervisory control and data acquisition sends control signals to a valve direct current control and protection system according to working condition requirements; 2) a PCP (Pole Control and Protect) control system in the valve direct current control and protection system calculates and generates periodic three-phase modulating wave signals according to a PCP operation cycle, and sends the three-phase modulating wave signals to a VBC (Valve Base Controller) control system and a synchronous control system; 3) the synchronous control system calculates and obtains a synchronous control cycle according to operation cycles of the PCP control system and the VBC control system, and performs once synchronization of the PCP control system and the VBC control system every synchronous control cycle; and 4) after the VBC control system receives the three-phase modulating wave signals sent by the PCP control system or triggering signals sent by the synchronous control system, a new VBC operation cycle is started, and the VBC control system performs processing of the received three-phase modulating wave signals. The flexible direct current power transmission technology pole control and protect and valve base controller synchronization system and method can be widely applied to the field of flexible direct current power transmission technology.
