Abstract
The STC (Synthetic Test Circuit) is the test circuit for operational tests of high power thyristor valves recommended by CIGRE as an alternative to the back to back test circuit. When adopting the fully controlled 3-phase thyristor rectifier as the key component of the power source, the mathematical model and the working theory of the power source are similar but not the same as the rectifier used in HVDC. The topology and the working principle of the power source are provided, and the qualitative analysis of two different operation modes of the power source are given by using EMTDC, then the mathematical model and a detailed analysis of the continuous recharging mode are proposed. And finally some calculation results under real working conditions and key parameters determination principles were given. A practical analysis method is provided for fully controlled 3-phase rectifier with time-variable loads.
