The invention relates to an active power filter control and communication system in the power system and power electronic technology, in particular to an active power filter control and communication system adopting the Concerto+FPGA framework. The active power filter control and communication system comprises a signal preprocessing module, a hardware protecting module, an I/O extension output module, an optical fiber driving module, a communication module, and a main controller module consisting of Concerto+FPGA, wherein signals are transmitted to the main controller module through the preprocessing module; after calculation through a series of algorithm, the connection and the disconnection of a switching tube of an inverter in an active power filter are controlled through an I/O control interface module and the optical fiber driving module; the protecting module is used for realizing the system fault protection; the communication module realizes the real-time parameter display and the remote monitoring of the active power filter through a CAN (Controller Area Network) bus.
