摘要
Abstract
The main functions and features of Risk-analysis and Decision-support System of Ningbo Power Grid are introduced.The theory of risk is presented.Component outage model is established based on historical statistical data.Thus the probability of grid state in a certain expected-fault is calculated.The operation state of the power grid can be described by quantitative risk index, combined results of expected-fault analysis and state probability.To make the results more consistent with the actual situation of the power grid, action logic of automatic devices, such as bus bar automatic transfer switch and transformer overload shedding device, is simulated in the power grid analysis.The system can assess the risk of grid online operation based on EMS, otherwise, it can calculate the risk of each maintenance plan offline and provide decision-support for dispatching operation and maintenance scheduling.As can be seen from the online operation, the system can guide the work of Ningbo Grid effectively.关键词
