摘要
针对风电接入的配电网后,原有的保护装置的保护范围和灵敏度发生变化,引起保护误动的问题,提出了一种适用于配电网的自适应保护设计,并通过计算仿真验证了设计原理的正确性。结果表明:该设计实时地反映了风电场接入对配电网的影响,使保护整定值自适应,保证了保护的可靠性和灵敏性。
After wind power access to distribution network,the range and sensitivity of the original protection device may be about to change,cause protection device misoperation. Aiming at the problem, puts forward a kind of adaptive protection design that is suitable for distribution network, and verifies the correctness of design principle by calculation and simulation. The result shows that the design can reflect the influence of wind-farm access to distribution network at real time, makes the protection setting values adaptive ,and ensures the reliability and sensitivity of the protection device.
