Research on SVG Reactive Power Compensation Device Based on DSP
Abstract At present, as the rapid development of power industry, A very wide range of high- voltage transmission network has been gradually formed in china, reactive power is also very important for the normal operation of the power system, so the attention to the reactive power should be changed。
The development of reactive power compensation device is described in this paper, and the traditional reactive power theory and instantaneous reactive power theory are analyzed too , the concept of instantaneous current and power is also introduced。 Instantaneous Reactive Power Theory and Its Key reactive current sensing applications based analysis and detection algorithm, test and verify the hardware and software on the feasibility of SVG apparatus, instruments used in this paper is the company's products (TMS320F2812 controller chip) respectively the main design of hardware and software components, which are part of the hardware from the main circuit and a signal conditioning circuit detection as well as the control circuit, some part of the main program module, controller module, PWM and sampling module can be used by the software。
