Abstract: Large power equipment in the use of the security problem is becoming more and more particularly to the network of electric power safety risk most affected, light person freezes or misoperation caused by equipment, heavy equipment com?ponents damage, cause great potential safety hazard to large power engineering. For this, put forward the risk control of large power network abnormal fluctuations model simulation, through the analysis of the for the large-scale power system network for network anomaly inspection, the large electric power network is decomposed into smaller sub network, each net?work at the boundary of the segmentation for equivalent calculation, by calculating the value of risk assessment and the es?tablishment of control model, abnormal risk control process of electric power network. Simulation experiments show that large electric network abnormal volatility risk control model of simulation can effectively improve power security control, re?duce the safety risk and have simple fault and the performance of complex fault, accelerate the speed and accuracy of risk assessment and strong reliability. Effective for large electric network provide a better risk control abnormal fluctuations.
