When the generator produces electricity, if no electrical devices are using the electricity, where does the electricity go?
According to this statement, if no electrical appliance is using electricity, that is, if there is no load, then the generator will not produce electricity . At most, the generator will idle at the lowest speed and do so. does not generate current electricity, there is no problem of excess electricity. In short, electrical energy cannot be stored in this system.
From the perspective of the national grid as a whole:
If electricity consumption is simply divided into several processes, then it is roughly electricity production , the electricity network and electrical equipment. The role of the power plant is to produce electricity at all times, and the role of the power grid is to transmit and distribute electrical energy. The electricity networktrique is a national network. It can monitor power consumption at any time, allocate power reasonably. return to the power plant the amount of energy to produce, so the general situation is that it generates as much electricity as it needs, and there will be no excess electricity.
During a day of electricity consumption, the electricity consumption situation is different in each period. The power grid will monitor these changes at all times and allocate electricity reasonably based on the number of electricity users during this period. decreases, then the power grid The power plant will be informed to reduce electricity production.
During the peak period of electricity consumption, the production units operating normally are not enough, so more production units must be put into service. This is the unit ofpeak peaking when the electricity network is overloaded. These regulating units The peak unit will operate. In short, peak regulation consists of maintaining the stable operation of the electricity network and better guaranteeing the quality of users' electricity consumption.
To put it bluntly, the power grid is the boss, and each power plant is the younger brother. Each power plant must be connected to the electricity grid and obey the unified deployment of the electricity network. You have to do whatever the power grid tells you to do. As part of the deployment, the dynamic balance of the entire power supply process is maintained. Basically, the energy generated is immediately used, and as much energy is generated as is used. basically, no excessive power.
About the role of pumped-storage power plants
Its main function is to regulatepeaks and troughs to maintain the stability of the overall operation of the electricity network. For example, when electricity is supplied. the grid is under high load, pumped storage power plants can be used to generate electricity to reduce the load. When the electricity grid is operating at low load, the pumped storage plant pumps water from low places to high places for storage, that is, it converts electrical energy into gravitational potential energy of water, such as when the power grid is under high load. mentioned above, it can open the door to release water, and the water flows from high places to low places to generate electricity.
Why do this?
Essentially, it is for the stability of the electricity grid. If there is no pumped storage power plant, what should we do when the grid loadpower is weak. Should we still leave the generator running? define a mediator? Basically, power plants are If the generator set is turned on and off frequently during continuous operation, it is not conducive to the stable operation of the power grid.
When the real-time daily load curve of the power grid tends to be flat, this is stability. To put it bluntly, the peak shaving and valley filling function of pumped storage power plant is to return stability. the overall curve tends to be flat.
The role of pumped storage power plants when the network load is lowIs it equivalent to storing electrical energy?
You can say that, even if it's not very precise. Because pumped storage power plants convert electrical energy into the gravitational potential energy of water.
Back to the topic, if there is no electrical equipment at all, then the generator will not produce electricity and there will be no problem of unnecessary loss.
Generator short circuit.
Generators (generators) refer to mechanical equipment that converts other forms of energy into electrical energy. It is driven by a water turbine, steam turbine, diesel engine or other electrical machines and burns water. flow, air flow and fuel. Or the energy generated by nuclear fission is converted into mechanical energy and transmitted to the generator, which is then converted into electrical energy.
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, thus generating an induced effect. electric potential, which isdischarged through the terminals and connected to the circuit, an electric current is generated.
Generators are widely used in industrial and agricultural production, national defense, science and technology and daily life. There are many forms of generators, but their operating principles are all based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its construction is: using suitable magnetic and conductive materials to form magnetic circuits and circuits that conduct electromagnetic induction among themselves to generate electromagnetic energy and achieve the conversion goal of energy.
