Human errors in the maintenance operations of power transmission grids can be a critical factor in the failure of equipment. Equipment failures result in the reduction in reliability, customer satisfaction, and loss of power companies revenue. In order to prevent the failure of equipment due to human errors, the supervisors or head of the operating groups needs to monitor the actions continuously during and after the maintenance. The proposed approach in this paper is to estimate the probability of the human errors’ effect in any failure with its technical and economic consequences for power companies. Then, the equipment failures have been categorized based on the risk assessment of the human error and consequences in order to identify high-priority tests or inspections for accuracy for monitoring and controlling.

通过识别和评估维护操作引起的故障风险来提高电网人员的可靠性

输电网维护操作中的人为错误可能是设备故障的关键因素。设备故障会导致可靠性、客户满意度和电力公司收入损失的降低。为防止设备因人为失误而发生故障，主管或操作组组长需要在维护期间和维护后持续监控操作。本文提出的方法是估计人为错误对电力公司技术和经济后果的任何故障影响的可能性。然后，根据人为错误和后果的风险评估对设备故障进行分类，以识别高优先级的测试或检查，以实现监控和控制的准确性。
