Power generation and grid connection refers to the process of paralleling the generator and the electrical system. Numerous power plants, substations, transformation and distribution equipment, transmission lines and electricity users make up the electricity system. The principle of grid connected generators, in simple terms, is based on the principle that when the voltage, phase, phase order and frequency are the same, they can operate in parallel. For example, it is like water from a river flowing into the sea slowly and without impact. When the generator is put in parallel with the system, it begins to transmit electrical energy to the electrical system, which means that the electricity generated by this power plant begins to be "generated for the grid". In other words, the water from the river begins to flow into the sea.
Regarding thepower generation switching, I think the term you mentioned is not specific enough and it should be power switching. This means that when the power supply to an electric power user is interrupted due to a fault, the power supply is automatically or manually switched to the emergency power supply. This process is called power switching. To achieve power switching, two different power supplies are required. To give a simple example, it is as if a person's clothing is broken and they can only wear another item of clothing. As for the principle and process of automatic power switching, it is very complicated.
What should I do if a small hydropower plant is not allowed to be connected to the grid?
Hydropower plant units must meet three conditions before they can be connected to the grid?es to the network to produce electricity: voltage, frequency and phase. If these three conditions are not met, it will not meet the electricity generation requirements of hydropower plants stipulated by the state. It cannot be connected to the grid for power generation, otherwise when connected to the grid, the voltage frequency phase will conflict with other power grid industries, and a unified standard current will not be formed, which which will have a great impact on the user's motors and devices.
Call and file a complaint. If it is State Grid or China Southern Power Grid, you can dial 95598 and follow the phone's step-by-step instructions to file a complaint. According to people who have complained, it works great. For small-scale hydroelectric power generation, you need to obtain relevant approval procedures and then apply to the supply companyelectricity ture for application, investigation, design and construction. After passing inspection and acceptance, the electricity supply company approves the connection to the network. it can be connected to the grid for electricity production. When connecting to the grid, it must be consistent with the power supply and the power line voltage, phase sequence and frequency must be the same before it can be formally connected to the grid. grid.
