摘 要:
从用电负载方面对目前太阳能光伏电站普遍存在的问题进行分析，着重指出了非线性负载所产生的电流畸变、高次谐波和高频干扰是对供电系统造成危害的主要因素。文章从负载和供电2个方面提出了改善措施：第一，使用高功率因数、低畸变的高性能电子节能灯具；第二，在逆变器中采用谐波抑制电路和有源功率因数校正电路对高次谐波加以处理，在供电设备端主动对流入的高次谐波和畸变电流加以处理，使负载功率因数提高到0.9以上。[著者文摘]

Abstract:
The paper analyzes the general problem in PV station in the view of power load, mainly puts forward the factors that endanger the PV power supply system, which are the current aberration caused by non-linear loads, high harmonic and high frequency interference. From two aspects of the load and the power supply, the paper brought forward the improving measures： firstly, use high efficient electron energy-saving lamps with high power factor and low aberration; secondly, in the inverter, adopt harmonic to control circuit and active power factor corrector for adjusting high harmonic, adjust the influent high harmonic and aberration current in the terminal of power supply equipments for increasing the power factor of loads over 0.9.[著者文摘]
