As we all know, the use of LPCS2000B scenery developed solar photovoltaic power plant power inverter system, the main function is to convert solar issued by the DC reverse into three-phase AC fed into the grid. And quickly resolved and the maximum inverter conversion efficiency, harmonic interference.
Use LPCS2000B develop solar photovoltaic power plant scenery inverter gridtiepowerinverteronline system, the main function is to solar issued by the DC reverse into three-phase AC fed into the grid. And to address the largest grid-conversion efficiency, harmonic interference protection and other issues. The control section controls the power function of the completion section generates a voltage in phase with the grid, and to track the actual output power, the power output power and maximum output power of the solar cell is equal.
Control part is LPCS2000B power control panel, control panel key device is Ti company's industrial DSPTMS
320F2801. Through multi-channel high-speed
DSP ADC sampling are used to monitor the grid voltage, solar battery terminal
voltage, solar cell output current, DC voltage regulator output voltage.
Meanwhile, DSP generated for the regulator and commutation of the switch
action, generated sine wave output. System can be controlled via the local
control panel, while providing RS232 interface-based remote control.
By the 50Wp polysilicon solar modules, composed by 24 modules in series, nine sub-matrices in parallel. Open circuit voltage DC510V, short-circuit current DC
27A, optimum operating voltage DC408V, Optimum
operating current DC 25A, the
solar cell generates DC voltage modulation is 100Hz, 220V (RMS) of the bread waveform.
The 100Hz unipolar waveform commutation bread became 50Hz bipolar ac waveform.
Through the three-phase transformer, coupled with the transmission network.
