Design and implementation of TMS320F2812 digital control system based on DSTATCOM

With the improvement of power quality requirements in the fields of iron and steel, metallurgy, mining and electrified railway, Distribution Static Synchronous Compensator (DSTATCOM) has been widely used in the distribution network. When DSTATCOM has been put into operation, there are many common problems such as not ideal dynamic performance, poor anti-interference performance and so on. Aiming at these problems, this paper takes the sliding mode control algorithm as the core, uses TMS320F2812 as a platform, and implements digital control system based on DSTATCOM. The experimental results show that the system has the advantages of good dynamic response, strong anti-interference ability and good current ripple suppression. Meanwhile, the system will have good application value in the future.
