I have a requirement for a PWM based three phase Micro Hydro Controller or ELC to be designed and prototyped. The ELC( Electronic Load Controller) is intended to control the voltage and frequency of a synchronous generator of a stand- alone micro hydro power generator. The generator frequency variation is in inverse proportion to the loading condition where ELC maintains constant loading of generator. The IGBT based DC chopping method is used for diverting excess power to the dump load using microcontroller for frequency sensing & control signal generation. The sensed frequency variation, is the reference to PWM signal generation, for the gate control of IGBT. Given below are my requirements for the Controller: 1) The ELC is intended to control a three phase synchronous generator. 2) IGBT will be used for diverting excess power to the dump load. The IGBT can handle up to 500 Amps. 4) In case the dump load is damaged/disconnected or the IGBT malfunctions or the main board malfunctions and it can no longer divert excess power to the dump load, then the frequency will rise. This can damage the equipments connected to the generator. A circuit need to be built in to disconnect the user load by means of a solid state relay/contactor in the event of over frequency or under frequency. 5)Total harmonic distortion of the sine wave should be less than 5% 6) Isolate the IGBT sufficiently using opto couplers and snubber circuits. Fast switching of IGBT generates significant radio interference. Please ensure that this does not impact the performance of the ELC 7) I also need the schematics, part list, PCB layout& design, source code etc of the ELC 9) The project will be completed when the ELC is working satisfactorily in all [login to view URL] iterations might be required to get the ELC working correctly. I have a Pump driven Micro Hydro Turbine setup. We will discuss finer details of the project once you are ready to take up the project. NOTE: PLEASE DO NOT ASK ME TO RELEASE MILESTONES BEFORE COMPLETING THE PROJECT. ACCEPT THIS PROJECT ONLY IF YOU ARE OK WITH THIS.

Hello, Based on the several clear drawbacks of the ELC method to attain a constant output frequency with varying user loads and water pressure, I’d like to ask: Have you explored alternative ways? Two come to mind: 1) a rectifier followed by an inverter, commercially available off-the-shelf in any voltage and power range. Benefits: no bulky dump load, no waste energy, precise output frequency. Cheaper than an ELC. 2) is even simpler, much cheaper and highly efficient overall: a controlled spigot before the turbine entrance. It would avoid the waste of any energy including the potential energy (water). Pure sinewave, bcs. no HV commuting, no critical technology: just a clever control algorithm, some electronics, and a servo drive with limited power. I could do that turnkey, and with enthusiasm! Thank you, best Regards -v8volante PS: Ignore the milestone put in by freelancer. Apparently there is no way to avoid it.

Hello, I am an electromechanical and electronic technician, and I only have the thesis to be an electronic engineer. I work in an electrical testing laboratory, under international standards, im work here for more than a year ago. I have worked with power electronics, I have developed direct current sources and inverters up to 6kVA for tests with inverters connected to the network. (These devices were presented at an engineering congress and awarded) (I can give you the magazine where it was published, keep in mind that it is in Spanish) I have experience in electronic design. If you want to know something else, do not hesitate to contact me I think it could be of great help for your project. I am already at your disposal. regards
