“…The studies in [3,26] verify and analyze the effects of human error on power system reliability and conclude that it is essential to consider human factors when determining maintenance policy. It has shown in [14] that the two reliability indicators of LOLP and EPNS in power system increase with human error.…”

The requirement for reliable electrical energy supply increases continuously because of its vital role in our lives. However, events due to various factors in the power grid can cause energy supply to be interrupted. One of these factors is human error and thus human reliability analysis is a serious element in the industry. The first step is to identify the roots of human error, on which there has been limited research in this area. In this paper, the potential and actual causes of human error in maintenance teams of power transmission system protection are identified and predicted within a framework of human factors analysis and classification system method. Then, human error factors are ranked to help improve human reliability. The proposed method is implemented in the Fars Electricity Maintenance Company.

“…Most of these analyses attempt to find the technical roots of equipment failures and solutions. However, less attention has been paid to the investigation of human error in the power transmission industry [3,4]. Surveys show that human error can affect the safety of personnel and equipment, as well as reduce the reliability of the network.…”

“…Human factors involve gathering information about human abilities, limitations and other characteristics and apply it to tools, machines, systems, tasks, and environments to produce safe, comfortable, and effective human use [3]. Existing literature has shown that human errors are major causes of incidents occurred in electric power system [4], railway [5], [6] and so on. Thus, in SMPS designs, we need to highlight the significance of assessing human performance to reduce human error with the consideration of both technical factors and human factors.…”

Fuzzy Cognitive Maps-Based Switched-Mode Power Supply Design Assistant System

Traditional engineering design approaches primarily solve technical problems and often ignore the importance of human factors. To reduce human errors and workload in power electronics, this paper proposes a switched-mode power supply design (SMPS) assistant system based on Fuzzy Cognitive Maps (FCMs). This system incorporates both technical requirements and human factors that involve designers' knowledge and skills in the SMPS design domain. First, we identify the critical concepts from power management lab kits and power electronics books, and extract latent sub-skills of SMPS design using exploratory factor analysis to build the starting concept list of FCM. Second, we use factor analysis and correlation analysis to determine the causal weights between the captured components to build initial FCM based on the starting concept list of FCM. Third, through interviews with subject-matter experts, we get their inputs on the initial main map and capture their individual FCMs. Then, we integrate experts' individual FCMs with different weights. After that, we determine the degree of fuzzification of the threshold function through analyzing data collected based on the prediction results of the only decision concept in the proposed FCM-SMPS quality. Two WHAT-IF scenarios are analyzed based on different inputs using the FCM Expert tool. The scenario test results provide guidances to designers in terms of knowledge or skills improvements and power supply debugging. Finally, we evaluate the proposed system using eight scenarios. The evaluation results of components' actual states are consistent with their preferred states, which suggests that the proposed FCM-based assistant system is reliable and effective.
