Grid Tie
Hello.
I'm from Poland, so sorry for grammatical errors. My English is not very good.
I have a wind power plants with a capacity of 1kW at 24V. I have control made by me (
www.wintechenerg.com). All the power is usin 'for charging. At present, the technical condition of the batteries is disappointing, therefore, I want to do the layout of the transmitting power to the grid.
I made the system according to the attachment, and I have a serious problem. Once connected to the transistors, into a zero crossing, I have all the time short circuit.
The system, instead of giving energy, gets a lot more when you connect to the installation of a windmill. Transistors strongly heat.
After a few attempts to opto-isolator system has been destroyed, so plugged into the control voltage transistors from a different transformer connections. It has two windings 15V and also 9V. I just used a 9V to control.
Please inform me whether in this form, the system connected to a wind turbine should be working properly?
Dvinchy posted schematic, but the effect is the same.
