检修状态下运行方式的制定对降低电力系统风险及确保电网的安全运行显得尤为重要，将风险理论应用于检修方式下的地区电网运行风险评估，根据地区电网运行特点，引入分层、分区评估的理念及可行运行方式集的生成方法；提出地区电网的运行风险指标，并计及备用电源自动投入装置对失负荷的影响的基础上，利用事件发生概率和后果形成风险矩阵，找到风险值最小的运行方式。最后实际电力系统检修时运行风险评估案例分析验证了该方法的有效性。

It is especially important for decreasing power system risk and guaranteeing safe operation of power grid to deter-mine the operation mode in maintenance state.The risk theory is applied for evaluation of regional grid operation risk in ma-intenance state.According to operating characteristics of regional grid,the paper introduces ideas of layering and zoning e-valuation as well as collection of feasible operating modes;it proposes operating risk index of regional grid and forms risk matrix by using event probability and consequences on the basis of considering the effect of BZT on load loss and gets the op-erating mode with minimum risk value.Ultimately,the method is proved to be effective by operation risk evaluation example in actual power system.
