Such as electricity enterprises, the performance and reliability of the machines are better than people. The main weaknesses in the system are the performance of people, people once exposes the weaknesses, the entire system would be in danger of collapse. Automation has become a trend in today's scientific and technological development as the main theme, in order to safeguard the safety of the system, we have to research the weaknesses and limits of people. Therefore, the study of mental workload level on the performance is help to improve the system's efficiency.The thesis studies the mental workload of the electric operation staff.
