【摘要】 利用ADMC401的三相16位PWM调制输出功能、灵活多样的接口方式及其高速的DSP计算速度,实现了电力系统中静止无功补偿器(STATCOM)的控制。考虑到控制系统的实时性要求,该控制系统采用了DSP和单片机组成的双CPU接口方式,保证了系统运算和控制的高速响应能力。同时,ADMC401具有专用的看门狗控制逻辑,可有效保证系统运行的可靠性。更多还原

【Abstract】 Guangdong Using the three-phase 16-bit PWM generation unit, flexible interface m odes, and high speed DSP calculation, the control system of static var generator (STATCOM) is realized. Considering the real time requirement, the control boar d is designed with double CPU system which is made of DSP and singlechip micro p rocessor, the fast response ability of calculating and controlling is ensured . Furthermore, the watchdog logic of ADMC401 could ensure the operation reliabil ity.更多还原
