If they are not consistent, there will be a frequency difference, which will cause a pulse voltage. In the cylinder of the diesel engine, the clean air filtered by the air filter is fully mixed with the high pressure atomized diesel fuel injected by the injector.
Under the upward pressure of the piston, the volume decreases and the temperature increases rapidly, reaching the ignition point of diesel. Diesel ignites, the gas mixture burns violently, rapidly expands in volume and pushes the piston down, which is called "work".
Detailed informationWhen abnormal noise, odor, sharp increase in water temperature, sharp drop in oil pressure, etc. occur. occur during operation, the machine should be stopped immediately for inspection and troubleshooting. The generator power factor should not exceed 0.95 in late phase (lag). The variation range of the freq valueuence should not exceed 0.5 Hz.
Before shutdown, you should first turn off the main switches of each power branch and gradually reduce the load, then turn off the main switch Main generator power supply, return the excitation rheostat to the maximum resistance position and reduce the voltage to the lowest value. Turn off the excitation switch and the neutral point grounding switch, and finally stop the internal combustion engine.

It is not illegal to purchase a small power 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 declare to the services concerned and submit the technical datas 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 prime mover, and then converts it into electrical energy. 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, scienceand technology and everyday 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 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 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 excitation generatorson CA:
1. Operating in variable speed and constant frequency mode
2. Mode Range setting method;
3. Operates in electrical energy production mode.
Article 19 of the “Electricity Law of the People's Republic of China”: electric power enterprises shall strengthen production safety management, adhere to the safety policy of first and prevention first, and establish and improve production responsibility for safety. system.
Power companies should carry out regular inspections and maintenance of electrical protection to ensure its 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 requiresthat the electricity it produces is 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 consensus through consultation in case of dispute. failure of network-connected parties; To reach an agreement, the energy management department at the provincial level or above will make a coordinated decision.
