The coil power supply is the core system of the EAST (Experimental Advanced Super-conducting Tokamak) device. In the field of nuclear fusion, the MDSplus database is often used to store experimental data and the built-in GUI tool jScope to display the experimental data. jScope can not meet the debugging needs. Based on the MDSplus database and the Python programming language, this paper develops the data analysis module of the power system of the EAST device, establishes the Python and MDSplus database interfaces, reads the data generated by the power system from the model tree, and calls the matplotlib package for waveform drawing. Visualize the power system data through Python, view the curve of voltage/current over time, obtain the difference, maximum, average, etc. of the voltage/current in any time period, and at the same time, you can read the relevant parameter values at any time point. The operation of the system plays a more precise and targeted debugging.
