基于典型故障限流措施的输电系统可靠性评估
Power transmission system reliability assessment based on typical fault current limiting measures
摘要
Abstract
The fault current limiting measures used in current power grid can control the short-circuit current effectively, and reduce the power distribution reliability and security margin of the system. With the continual increase of the short-circuit current levels,it′s necessary to research the more effective alternative method. The basic fundamental of HVDC and traditional short-circuit current limiting measures are analyzed to establish the corresponding AC/DC current equation and reliability evalua-tion model. The effect of the DC power control on status adjustment link after Monte Carlo fault is considered in evaluation pro-cess. The system reliability indexes are compared under the influence of different measures. The affects of HVDC installation lo-cation and DC capacity on reliability are studied. The simulation results show that,in comparison with the traditional measures changing the system structure such as bus segmentation and cut-off transmission line,the HVDC has higher system reliability un-der the same current limiting effect.关键词
