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 DSPTMS320F 2801. 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 DC27A , optimum operating voltage DC408V, Optimum
operating current DC25A , 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.
