摘要
数字化变电站实现了保护之间的信息共享,简化了复杂的二次回路接线。而如何简化保护的网络配置,使数据在网络中可靠传输成为所要探讨的重要问题。对3/2断路器接线方式下所配置的断路器保护进行了分析探讨。针对断路器保护不双重化配置但出口双重化这一特点,根据保护间的信号联系,分析了继电保护GOOSE网络方案,提出了集中式断路器保护网络配置方案,同时对集中式断路器保护功能进行了说明并分析采样值的传输数率。最终确定保护网络配置方案。
The information of digital substation is always use network which is easy to implement information sharing between the protection and made the secondary wiring of the system simply. How to make network configuration simply and data transmission reliably is have to discuss. The breaker protection in 3/2 structure is analyzed. According to the feature of protection that the configuration is not double but the output of protection is double and the contact between the breaker protection and the other protection, the GOOSE network solution is analyzed and the centralized network configuration program of breaker protection is proposed. Then the concentrate breaker protection function is illustrated and the rate of transmission of samples values is analyzed. Last the network configuration program of protection is determined.
