It is not illegal to purchase a small wattage hydroelectric generator for your own use.
If the power plant needs to be connected to the power grid to absorb and transmit electrical energy and failure to comply with the standards will cause negative effects on the external power grid and endanger public interests, it must report to the relevant departments and submit the technical data for review and approval. The power plant will be inspected on site to verify safe operating conditions. Once all inspections have been passed, a certificate will be issued before the power plant can be operated.
A generator refers to a mechanical device that converts other forms of energy into electrical energy. A general generator converts the energy contained in various primary energy sources into mechanical energy through a main engine, and then converts it into electrical energyctric. energy by the generator, sent to various places of energy consumption via the energy transmission and distribution networks. Generators are divided into DC generators and AC generators. Their operating principles are based on the law of electromagnetic induction and the law of electromagnetic force. They are widely used in industrial and agricultural production, national defense, science and technology and daily life.
Generators are generally composed of stators, rotors, end covers, bearings and other components. The stator consists of the stator core, wire windings, machine base and other structural parts that secure these parts. The rotor is composed of rotor core winding (or magnetic pole, magnetic yoke), retaining ring, center ring, slip ring, fan and a rotating shaft. The stator and the rotor of the generator are connected and assembled by the bearings and end covers, so that the rotor can rotate in the stator and carry out the cutting movement of the magnetic lines of force, thereby generating an induced electric potential, which is evacuated. across the terminals and connected in the circuit to generate current.
There are three main modes of operation of AC excitation generators:
1. Operating in variable speed and constant frequency mode
2. Mode Range setting method;
3. Operates in electrical energy production mode.
Legal basis
Article 19 of the “Electricity Law of the People's Republic of China” Electric power enterprises should strengthen management of safety production and adhere to safety first. and prevention policy first, establish and improve the production responsibility system in mattersre security.
Electricity companies should carry out regular inspections and maintenance of electrical installations to ensure their normal operation. Article 22 The State promotes the parallel operation of electricity generation companies and electricity networks, as well as electricity networks and electricity networks. If an electricity production company with independent legal personality requires that the electricity it produces be connected to the network for its operation, the company operating the electricity network must accept this.
Grid-connected operation should comply with national standards or electrical industry standards. The parties connected to the network will sign a network connection agreement to determine the rights and obligations of the two parties in accordance with the principles of unified distribution, hierarchical management, equality, mutual benefit and consensusus by way of consultation in the event of failure of the parties connected to the network; To reach an agreement, the energy management department at the provincial level or above will make a coordinated decision.
