1. Gas Turbine: Gas turbines typically operate at high speeds of tens of thousands of rpm.
2. Steam turbine: The speed of the steam turbine is relatively low, usually around 3000 rpm.
3. Hydro-turbine generator set: The speed of DC type hydro-turbine generator set is relatively high, generally above 500 rpm. The rotation speed of the AC turbine generator set is relatively low, generally between 150 and 300 rpm.
How does isolated grid technology save energy and reduce emissions?
Isolated Grid: Refers to an independent power grid that is not connected to the national grid, or a small power grid that is detached from the national grid for some reason and operates independently.
Self-powered electrical network: refers to a networkisolated electricity formed by a company's own power plant without being integrated into the national grid.
Public Grid: refers to the State Grid (including China Southern Power Grid).
Direct power supply: refers to the situation where electricity is supplied directly from the power plant without passing through the power grid.
How to charge a hydroelectric plant when operating on an isolated network
1. It is suitable for stand-alone power plants whose total electricity production is slightly greater than or equal to that of the enterprise. electricity consumption. For example: a ferrosilicon factory has an autonomous power plant with an installed capacity of 4*12 MW. The ferrosilicon plant has four 12,000 KVA electric melting furnaces or two 24,000 KVA electric melting furnaces. Using our company's technical equipment, it canrealize. stand-alone power plants and ferrosilicon plant operate on an isolated grid and do not need to be connected to the electrical system to operate.
2. Suitable for newly built stand-alone power plants. Due to state restrictions on small thermal power plants, it is difficult for power generation companies to connect to the grid, or the power system charges fees of up to 2 to 8 cents/kWh for use the company's need to connect to the network. energy production. After using our company's technology, when the company's internal power consumption and power output fundamentally match, the stand-alone power station can realize isolated grid operation and be self-sufficient without the need to connect to the network. It can independently establish electricity. price and reduce myso high billed by the electricity service. Costs saved. Based on the experience of operating a 2*12 MW power plant in an isolated grid using our company's patented technology, it can save about 30 million yuan in electricity payment fees per year, bringing considerable benefits to your business.
3. Applicable to small captive thermal power plants that have been connected to the grid for electricity production. Due to rising coal prices and other reasons, the profit margins of corporate power generation are getting smaller and smaller. Through our company's technology, it can be decoupled from the power grid, allowing the isolated grid to operate stably and improving the economic benefits of the enterprise.
My own power plant is a newly built power plant
The operating methodof a hydroelectric plant on an isolated network with load is as follows:
1. First, several units operate in parallel to form a small network, not connected to the external network.
2. Second, there is a standalone charging mode with a single unit providing power.
3. Finally, the generator operating on the network is decoupled from the external electricity network, and once the load is shed, it only operates with the energy necessary for the factory. This is a special case of one. machine with load
National electric power regulations stipulate that no power plant may privately sell electricity for use by entities other than the same legal entity. For electricity consuming units and electricity production units which are the same legal entity, If the companies are listed in the table or belong to the same group, theCompanies are encouraged to provide their own power plants to be self-sufficient. Power grid companies are both businesses and not government agencies and do not have the right to impose sanctions on power plants they own. Since there has not been an isolated grid operating technology for a long time, once the power plant is built, it must be connected to the grid to operate reliably. This has led to self-built power plants being subject to constraints. electrical network company.
Some of the cases made by Shanxi Bosec were once grid-connected power plants. After successfully achieving grid-isolated operation, they were separated from the power grid company, but the power grid company was powerless.
