| 摘要: |
| 提出一种适用于谐波及无功综合动态补偿系统（HRIDC）的控制方法。HRIDC由注入式混合有源电力滤波器（IHAPF）和静止无功补偿器（SVC）联合构成。在分析HRIDC结构和原理、建立其电气模型的基础上，设计了一种由IHAPF复合控制和SVC模糊PI控制组成的HRIDC控制方法。IHAPF复合控制由分频控制和滞环控制构成。跟踪误差大时采用滞环控制，以提高响应速度；跟踪误差小时采用分频控制，实现零稳态误差控制。该方法有效综合了分频控制和滞环控制的优点，实现谐波的快速和无差跟踪。SVC模糊PI控制根据电网电压控制误差和模糊规则表在线调整PI控制参数，提高对无功控制的响应速度和控制精度。仿真和工程应用结果验证了所提出控制方法的有效性。 |

| Abstract: |
| A control scheme of integrated dynamic compensation system（HRIDC） is presented，which is composed of an IHAPF（Injection-type Hybrid Active Power Filter） and a SVC（Static Var Compensator）. Based on the topology and operating principle of HRIDC，its electric model is established and its control scheme composed of complex control for IHAPF and fuzzy PI control for SVC is designed. The complex control for IHAPF is composed of frequency dividing control and hysteresis loop control. The hysteresis loop control works to improve the response speed when the tracking error is large while the frequency dividing control works to realize zero steady-state error when the tracking error is small，by which the rapid and zero-error harmonic control is achieved. The fuzzy PI control online adjusts the control parameters according to the control error of power grid voltage and the fuzzy rules，which enhances the response speed and control precision of reactive power control. Simulation and application verify the validity of the proposed control scheme. |
