摘要:
对用分布式发电系统中的并网逆变器实现有源滤波与无功补偿功能进行了研究,提出一种基于负载电流检测的实现方案。检测到的三相负载电流经abc/dq 变换至同步旋转坐标下,对其d、q 轴分量分别进行高通和低通滤波并提取出负载电流的谐波与无功电流分量,然后与基波有功电流指令合成,得到逆变器的输出电流指令。电流跟踪控制采用“PI+ 重复控制”策略,保证了对输出电流指令的准确与快速跟踪。仿真结果表明,并网逆变器可以在输送有功电流的同时进行无功和谐波补偿,有助于电网电能质量的改善。
Abstract:
It researches on the implementation of active filtering and reactive compensation with grid-connected inverter in distributed generation system, and proposes a solution based on load current detection. The detected three phase load currents are transformed to the synchronous coordinate frame through abc/dq transformation, the harmonic and reactive components are extracted by a high-pass or low-pass filter from the d-axis and q-axis components. Then the output current references of the inverter are obtained by synthesizing the extracted currents with the fundamental active current. Output current control is realized by PI+RP compound control algorithm, which ensures the accurate and quick following to the reference. Simulation results show that the inverter could compensate reactive and harmonic currents and transfer the active power at the mean time, which is helpful to power quality improvement.
