Risk Assessment of Substation Main Connection Based on LCC Management

Abstract:

Life-cycle cost management is the foundation and techniques for life-cycle cost management. Petri nets has a graphical expression, can improve and add more features and information to Fault tree analysis, Markov equations and so on, raising the speed and accuracy of the entire system of risk assessment. The paper propose a risk assessment based on the life-cycle management approach, establish four state model to analysis transformer substation main wiring operation, discuss elements occurring planned maintenance events and breaker tripping phenomenon, and propose using the basic equations of Petri nets to determine system status and calculate the corresponding probabilities, quantitative analysis of the outage costs of the substation main connection off for running, and seek the best value under the run. In the example discussing and calculating the risk indicators of outage costs for different wiring schemes, the results demonstrate the feasibility of the proposed algorithm.
