Research On Some Problems In Distance Protection And There Training Simulation System Implement

Distance protection was widely used in high-voltage power system. A series of hotspot problems of distance protection was be researched detailed combined the situation of the distance protection application in this paper. It includes fault resistance,system swing,series capacitor compensation influence to distance protection, and fault phase selector. A new project that using math morphologic grads distill the character of transient current fault to identify trouble style and a new method that identifying surge and trouble were put forward. For satisfying the demand to the training of the worker, the thesis adopting object-oriented programming method opened out a simulate training system of computer distance protection equipment. The effect of which is actual , the function of which is self-contained and the practicability of which is strong. The trained persons can understand and grip the elements and using method of the set expediently, improve effect of training.
