LNGC series hydraulic grid-connected converter is a core power electronic device connecting hydraulic generators with power grids, responsible for key tasks such as power conversion, control, and grid integration. Its core function is to convert the non-power frequency and unstable electrical energy output by hydraulic generators into high-quality AC power synchronized with grid frequency and voltage, while achieving power optimization and harmonic suppression, ensuring efficient and safe grid-connected operation of hydraulic power generation systems. The hydraulic grid-connected converter adopts a DSP fully digital control scheme, equipped with touch screen and remote monitoring interfaces (RS485/WiFi/GPRS), enabling parameter setting, power curve adjustment, and multi-terminal data interaction. It is built-in with DC voltage regulation circuit, featuring boost-buck modulation function. The AC voltage generated by the hydraulic generator is first rectified by the rectifier circuit and then reaches the DC bus through the voltage regulation circuit. The inverter control circuit chops the DC bus voltage into pulse sequences with gradually changing pulse widths. The filter circuit filters and shapes to eliminate high-frequency harmonics, outputting smooth sinusoidal AC power. Grid synchronization (PLL) technology is used to real-time detect grid voltage phase and frequency, ensuring converter output synchronization with the grid. The hydraulic grid-connected converter employs MPPT (Maximum Power Point Tracking) technology as its key control strategy. By dynamically adjusting the inverter output current, the converter can output maximum power under different rotational speed conditions of hydraulic generators. The hydraulic grid-connected converter features efficient power conversion, high reliability, wide input voltage range, precise grid synchronization, comprehensive protection functions, advanced control technology, and optimized power quality. These characteristics ensure stable operation and efficient energy conversion of hydraulic power generation systems. Typical applications include grid-connected power generation in small and medium-sized hydropower stations, distributed hydraulic power generation systems, and hybrid energy complementary systems.
