Abstract: With the expansion of the power system scale, the demand for power system visualization is increasing in the recent of years. A stable operation of the power system is very important for people’s normal life. Operators have to monitor 4-5 screens at the same time to check the status of the system. Each screen contains thousands of transmission lines and thousands of different data. When one of the data is out of the safe range, the operator needs to take action and repair it in time. Otherwise, it will lead to a catastrophe. The goal of this thesis is to test whether the graphics visualization can be used in the power system and accurately communicate the data. A new visualization was created which included graphics to express data in the single transmission line diagram. Afterwards, a user study was conducted with 7 people, where the results showed that some data could be expressed in the image but not all of them. And the feature of image visualization was that it contained more useful information that could be easily understood by the operators.
