Wind (hydro) power generation grid connected inverter power supply

Product Introduction
The wind power grid connected power generation system consists of wind power, wind power controller, grid connected inverter, metering device, and distribution system. Wind energy is converted into direct current through wind power, and then converted into sine wave current with the same frequency and phase as the grid through grid connected inverters. Part of the current is supplied to local loads, and the remaining power is fed into the grid. It can be seen that wind grid connected inverters are key equipment in new energy generation systems.

Product Features:
1. The main control part is a fully digital control circuit, and the main control chip adopts TI's 32-bit DSP processor. The display part adopts a 7-inch touch screen, which is easy to operate;
2. Adopting SVPWM inverter, the maximum efficiency can reach over 96%;
3. The IGBT adopts Infineon's original imported modules, and the driver chip adopts Mitsubishi driver chip. The main components are selected from domestic and foreign first-line manufacturers to ensure stable and reliable operation of the power supply;
4. The power part adopts modular design, which is easy and convenient to maintain;
5. Built in fan power curve setting function, allowing users to modify the power curve themselves, facilitating on-site debugging, effectively matching fan parameters, and achieving maximum power generation efficiency;
6. It has multiple communication interfaces such as 485 and Ethernet, which facilitate system integration for users;
7. The interface and function upgrades are convenient and fast, meeting the changing needs of customers in the later stage and saving investment in the later stage;
