器系统的设计与仿真

摘要：随着时代的发展，技术的进步，各式各样的电⼒电⼦设备得到了充分的利⽤。⽆源滤波技术是过往常使⽤的抑制谐波与补偿⽆功功率的⽅式，此技术的优点有结构简单和造价低等，但与此同时也有很多不尽⼈意的地⽅。在电⼒、功率集成电路技术和相关的⼀些谐波理论的逐步成熟后，滤波的研究重点逐渐变为了有源电⼒滤波器(Active Power Filter)。其基本原理是：APF向电⽹注⼊与原有谐波和⽆功电流⼤⼩相等但⽅向相反的补偿电流，使电⽹的总谐波以及⽆功电流为零，它的⽬的是净化电⽹。APF能对变化的各次谐波和⽆功电流同时进⾏跟踪补偿，补偿特性受电⽹阻抗和频率变化的影响相对⽐较⼩，控制电路可以⽐较⽅便的完成限流保护，增加了装置的稳定性，减少了发⽣事故的概率。本次实验为并联型APF，利⽤MATLAB软件建模，它可以通过实时检测负载的谐波电流，控制VSC向电⽹注⼊与负载谐波电流⼤⼩相等但⽅向相反的电流，就能实现滤除谐波的功能。62204

The system design and simulation of active power filter

李逢鹏Abstract:With the rapid development of power electronic technology, various kinds of power electronic

equipment is widely used. The traditional method of harmonic suppression and reactive power compensation is passive filtering technology, passive filter technology has simple structure, and low equipment investment, but also the shortcomings and defects. With the Power electronic technology and Power integrated circuit technology and the development of the related theory of harmonic, people turn to the Active Power Filter will Filter research direction (Active Power Filter). Its basic principle is: injection APF to the grid and the original harmonic and reactive current is equal but opposite direction to the size of the offset current, make the grid total harmonic and reactive current is zero, so as to achieve the purpose of purifying power grid. It can to change every harmonic and reactive current tracking compensation, compensation characteristics affected by grid impedance and frequency change is small, the control circuit is easy to implement current-limiting protection in order

to improve the security of the system. This experiment for shunt active power filter, using the MATLAB software modeling, it through the real-time detection of load harmonic current, control VSC injected into power grid and load harmonic current equal but opposite direction of current, can realize the function of filtering harmonics.
