| Abstract: | According to modification project of USA 2300XP excavator in reactive compensation system, the paper introduces and analyzes characteristics and current questions of the excavator in original reactive compensation system, then through original thyristor switch capacitor （TSC） compensation strategy in the foundation, improves switch control strategy to enhance reactive compensation system robustness, and carries out the principle simulation. The results show that modified excavator runs effectively. |
