冲击负荷对电力系统可靠性影响的分析
Influence of Shock Loads on Power System Reliability
摘要
Abstract
Shock load exerts various negative effects on electric network and power equipment. Investigations were implemented with respect to this problem focusing on power system reliability. The basic outage model of normal equipment was analyzed under the assumption that shocks arrive following a Poisson process and with mutually independent magnitudes. The parameter of the expected first-run time was used to improve the reliability index of power equipment under conventional load. The system reliability under shock load was evaluated using the improved index. The effects of shock load on system reliability can be analyzed in detail through the comparison of the results obtained with conventional and shock loads. Simulation of a regional power system demonstrates that the proposed method is effective. This research provides a quantitative reference for operation risk analysis and maintenance scheduling of power systems under shock load.关键词
