在以光伏、风电等新能源组成的分布式发电系统中
恒功率负载的接入削弱了系统的阻尼
可能导致直流母线电压振荡
对系统稳定性及输出电能质量产生不利影响。传统方法通过并联大容量电解电容来抑制电压振荡
但电解电容存在内部损耗、体积大等缺陷
极大降低了功率密度和可靠性。针对以上问题
提出一种新型的功率振荡抑制装置及其控制方法
抑制装置中的辅助电容可有效吸收并存储直流母线的振荡功率
进而滤除直流母线上的电压谐波。相较于传统方法
所提抑制装置可有效滤除单次或多次电压谐波
具有适用性强、控制灵活等优势。最后通过仿真和实验验证了该方法的有效性。
In the distributed generation system composed of new energy sources such as photovoltaic and wind power
the access of constant power load weakens the damping of the system
which may lead to DC bus voltage oscillation and a negative impact on the system stability and the output power quality. The traditional method suppresses voltage oscillation by paralleling large-capacity electrolytic capacitors
but the electrolytic capacitors have defects such as internal loss and large volume
which greatly reduce power density and reliability. In view of the above problems
a new type of power oscillation suppression device and its adaptive control method is proposed. The auxiliary capacitor in the suppression device can effectively absorb and store the oscillation power of the DC bus
and then filter out the voltage harmonics on the DC bus. Compared with the traditional method
the proposed suppression device can effectively filter out single or multiple voltage harmonics and has the advantages of strong applicability and flexible control. Finally
the effectiveness of the proposed method is verified by simulation and experiment.
