1 The electricity generated by the hydroelectric generator must pass through transformers, circuit breakers, disconnectors, voltage transformers, current transformers, surge arresters, various protective devices, measuring devices and others equipment before it can be integrated into the electrical network. ; if the generator exports The voltage is the same as the voltage connected to the local grid and no transformer is required;
2 Grid integration requires the agreement of the local electricity bureau and various protections for the generator socket must be configured in accordance with the requirements of the electricity bureau approval documents. Measuring device in a box;
3 After being connected to the power grid, it is unclear whether it will be used by nearby businesses and residents. Because once electrical energy is integrated into the electrical grid, it is impossible to distinguishbetween that generated by you and that generated by others.
4 Electric grid companies generally do not allow generators to supply electricity directly to users; The power grid provides electricity to users and charges unified electricity rates. This is also true for distributed energy resources or photovoltaic plants. In addition, the production of photovoltaic energy is subsidized by the government, it is not integrated into the electricity network and does not benefit from subsidies on electricity prices.
You must first confirm the information:
1. How high is the water level? (This is the vertical height from the water inlet to where you plan to install the turbine generator)
2. How many cubic meters per second is the flow rate (or what the diameter of the water pipe might be). used to continuously supply water tou complete pipe)
3. Is the water source affected by the rainy season or the dry season? What is the flow during the dry season?
To understand the above points, you can consult the manufacturer of the micro hydroelectric generator, and they will recommend a suitable machine for you.
If it is a water source with low water head and large flow rate, the “volute axial flow turbine generator” is your best choice.
If it is a water source with high head and low flow, and the flow changes significantly in winter and summer, the "impact turbine generator oblique double tube and double jet" should suit you.
However, the principle is that you must first confirm the relevant information about your water source.
