接受的范围

• The last chapter 5 gives out the simulation pictures of apf under power system circumstances through borland c + + , the result proves that the new apf can efficiently compensate system line reactive power , the high harmonic during pwm can be controlled in acceptable scope . at last the conclusion is drawed at , and some flaw is pointed out
  第四章则给出了该apf在borlandc + +程序构建的电力系统环境下的仿真结果，从理论上证明了该新型apf可以有效的补偿系统无功和消除谐波，它在pwm过程中产生的高次谐波也被控制在可接受的范围内。
