| 摘要: |
| 针对传统发电机失步保护装置的误动情况,提出了一种基于广域测量系统(WAMS)的发电机失步保护与电网功角稳定的协调控制方法.该方法的稳定判据共包含2个部分:一部分仍采用传统的本地保护装置的信号;另一部分采用基于WAMS的暂态稳定在线预测结果.协调控制部分由一个中心服务器完成,若该中心首先收到保护装置的动作信号,则发出切机命令;若该中心首先收到暂态稳定在线预测结果为稳定的信号,则发出闭锁失步保护装置信号;若该中心首先收到暂态稳定在线预测结果为不稳定的信号,则根据预测的发电机功角轨迹,启动优化切机方案进行紧急控制.以新英格兰节点测试系统的仿真结果为例,证明了该方法的有效性和合理性. |

| Abstract: |
| Aiming at the malfunction of generator out-of-step protection,the coordination control between rotor angle stability and out-of-step protection based on WAMS(Wide Area Measurement System) is presented,the stability criterion of which has two parts: the local protection signal and the online prediction of transient stability based on WAMS.The coordination control is done by a central server:if the protective signal of local protection comes first,it sends the trip command;if the online predicted transient st... |
