This paper analyses the reactive power compensation and harmonic in power supply and distribution system of electric heater controlled by SCR phase shifting compressor governor device, and gives the accurate calculation formula of harmonic content and system factor, and the select methods of active filter and reactive power compensation. It concludes that only using reactive power compensation could not meet the demand of power grid in the aspect of system factor in non-liner circuit, and points out the key point of the solution is selecting technique scheme reasonably, and producing less or no pollution.
