摘要
先进的单桥路静止无功发生器(ASVG)存在的最大问题是自身输出的电流含有很大的谐波.通过对ASVG典型负载的仿真分析,提出了改进措施,并分析了原因,得出了改进后的仿真波形,极大地减少了系统的电流电压谐波含量,证明了该方法的可行性、经济和简易.文中还阐述了ASVG的硬件构成和数学推导过程、控制系统等.
The most serious problem about advanced single-bridge static VAR generator is its quantities of harmonic during PWM Through simulation of typical ASVG load,this paper puts forward a changed hardware structure and the reason is analyzedComparing the simulation picture with the pre-changed one,the probability, easiness and economy are seen for the changeThe hardware structure, mathematics model and control principle are also described in this paper
