Overview
Product Details
The on grid wind turbine converter adopts AC-DC-AC PWM rectification plus PWM full-bridge inverter two-stage circuit technology. The core control adopts dual DSP full digital control, and realizes the stator magnetic field oriented vector control strategy on the rotor side converter of power generation. The grid-side converter implements the grid voltage directional vector control strategy; the system has the functions of adjustable input and output power factor, automatic soft grid connection and maximum power point tracking control. The power module uses high switching frequency IGBT power devices to ensure a good output waveform. This rectifier inverter device has the advantages of simple structure and less harmonic content.
1. Adopt PWM rectification plus PWM full-bridge inverter two-stage circuit, which can achieve the characteristics of wide output voltage range, high precision and fast dynamic response;
2. Adopt the principle of PWM rectification + PWM inverter, power factor>0.99;
3. THD and injected harmonic current meet the national standard GB/T14549-93;
4. Complete measurement functions: voltage, current, current peak, frequency, etc .;
5. Save the fault function: support historical data query, automatically record the power status and alarm code at the time of alarm, greatly reducing maintenance time;
6. Touch screen, user-friendly design, no operation for 5 minutes, automatic black screen, parameter setting requires password entry, to prevent misuse;
7. 7inch color touch screen display, operating system data, fault information at a glance, convenient parameter setting;
8. Support RS485, WiFi, GPRS, Ethernet and other communication methods. You can monitor the working status in real time through the PC or mobile phone, and you can also query the historical working status. The mobile terminal is compatible with Android and IOS. All data can be connected to the Internet of Things.
