| The direct star of the indunction motor can generate several-fold rating current. Which will contaminate the power supply system and damage the motor itself. To improve the parameter in start of motor, a voltage adjusting model with SCR is used. The article discusses control method of high voltage soft starter and analyzes control model of adjust the voltage and limit the current by SCR throughout simulation of MATLAB. We design main control unit based TMS320LF2407 and monitoring unit based SIMENS PLC. In this article, we introduce design of 10kV thyristor valve. The real waveform and result of testing is given in later charpter. |
