Embodiment Construction
[0028] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0029] Such as figure 1 As shown, the chain-type SVG is connected in parallel to the bus BUS1 of the common terminal of the power supply through the step-up transformer T1, the first current transformer CT1 collects the current signal of the grid feeder FB1, the second current transformer CT2 collects the output current signal of the SVG, and the first voltage The transformer PT1 collects the voltage signal of the assessment point BUS1, the uplink control fiber LK1S transmits the status information of the valve body and the DC bus information to the control system, the downlink control fiber LK2S transmits the PWM pulse signal to the valve body, and the control system collects the first current transformer CT1, The information of the second current transformer CT2, the first voltage transformer PT1 and the uplink control fiber LK1S are processed and ...
