【摘要】:为解决有源网络的保护问题,对相关的断路器应用技术进行了研究。通过对电弧更有效的控制,实现直流断路器的开断能力与极性无关,使其满足光伏发电系统的保护需求。通过将真空灭弧技术与ACB操作机构相结合,提高断路器在AC690~1 140 V电压下的开断能力。通过对操作过程的有限元分析和优化设计,提高断路器的操作寿命,使其满足风力发电系统的保护需求。通过采用方向性的区域选择性联锁技术,解决了多电源系统中的选择性保护问题。运行经验表明,上述工作有效提高了有源网络运行的安全性。
[Abstract]:In order to solve the protection problem of active network, the application technology of circuit breaker is studied. Through more effective control of arc, the breaking ability of DC circuit breaker is independent of polarity, so that it can meet the protection needs of photovoltaic power generation system. By combining vacuum arc extinguishing technology with ACB operating mechanism, the breaking capacity of circuit breaker at AC690~1 140V voltage is improved. Through the finite element analysis and optimization design of the operation process, the operating life of the circuit breaker is improved to meet the protection needs of the wind power generation system. By using directional regioselective interlocking technology, the problem of selective protection in multi-power supply system is solved. The operation experience shows that the above work can effectively improve the security of active network operation.
