摘要
水机保护系统是水电厂十分重要的、不可缺少的组成部分,它和机组的继电保护系统一起构成机组的保护系统,对提高水轮发电机组的可靠性和安全性具有十分重要的作用。水轮发电机是水电站的重要动力设备,直接关系到电站及电网的安全,水电站应配置充分、合理、可靠的水机保护以保证水轮发电机设备的安全。通过对水机保护逻辑的全面排查和梳理,精心设计和优化跳闸逻辑,通过优化改造的实施,规避了控制原理风险,使机组水机保护误动或拒动的运行风险进一步降低,阿海水电站水机保护逻辑的可靠性得到了极大的提升。
Water turbine protection system is an important and indispensable component of a hydroelectric power plant.Together with the unit's relay protection system,it constitutes the unit's protection system and plays an important role in improving the reliability and safety of water turbine set.Water turbine is an important power equipment of hydro-electric power station,which directly affects the safety of power station and power network.Hydro-electric power station should be equipped with adequate,reasonable and reliable protection of water turbine to ensure the safety of hydro-generator equipment.Through thorough investigation and combing of the water machine protection logic,trip logic is carefully designed and optimized.Through the implementation of optimization transformation,the risk of control principle is avoided,and the operational risk of misoperation or refusal of unit water turbine protection is further reduced.The reliability of water turbine protection logic in Ahai Power Station has been greatly improved.
