First of allAC powercannot be stored, so the energy from the power plant can be used immediately. However, the relationship between the power plant and the user is not smooth. as much as it is generated but as much as it is used, use as much as you need, there is no waste.
There are two points that need to be emphasized here. First, it is a fact that electrical energy is wasted. How to explain it? used, it is generated? So when there are fewer users, the unit must either adjust. For small loads, when the minimum load cannot be maintained, it will be stopped. Therefore, for wind power, solar power, etc., where available. It's wind and sun but there is no load gap, either the generator or the solar panel must be disconnected. Everyone's talking about abandoning the wind and the lightera.
Hydroelectricity has no load during the rainy season. At the same time, when the water level of the dam is close to the high level, the valve will open directly to release the water, resulting in water abandonment. This is what we call abandoning wind, light and water in energy waste. The corresponding solution is to prioritize clean energy first, let thermal power plants adjust peaks or build pumped-storage power plants, use excess wind and photovoltaic power to pump the water from the bottom of the dam to the top of the dam, and then release the water to generate electricity in case of electricity shortage at peak.
This is what we're talking about to solve clean energy waste and balance the operation of the power grid through peak shaving, valley filling and energy storage. The second donation pointWhat I'm talking about is why it's possible to make as many shots as you use. In fact, that's the benefit of running a large power grid. The load flow of the electricity network is important. For example, if you suddenly turn on the hair dryer at home, the 1 kilowatt load will have no impact compared to the load. multi-million kilowatt load rate of the municipal power grid.
This doesn't affect it at all, but the peak morning power consumption and peak evening power consumption should have been more obvious in the early years, i.e. the lights during maximum power. Power consumption is not as good as usual, because the peak power consumption has caused the power grid to worsen. At that time, the generator needs to supplement the charge continuously. voltage surge.
Thus, the large electrical network pcould produce as much electricity as it consumes, which will increase the flow of the provincial network and ensure the stability and security of everyone's electricity consumption. Some may also argue that large industrial electricity consumers have little impact on the power grid, such as refining furnaces in foundries. For such powerful starting devices, those over a few hundred kilowatts will have starting procedures.
Depending on the start of industrial frequency conversion, the process time from 0 to 100 is enough to compensate for the power grid flow. Therefore, the above two points should be able to answer the question of why electricity is produced as much as it is used without wasting it.
Why is the water temperature of 100kw Cummins diesel generator set too high?
The temperature of the cooling wateris relatively high
(1) It is usually caused by the accumulation of dust on the radiator outside the cooling water tank. In case of heavy dust, debris on the outer surface of the radiator or during operation of the device will be sucked into the water tank by the cooling fan, causing blockage, blocking ventilation and resulting in poor heat dissipation. heat. At this point, you just need to clean the radiator outside the water tank and clean the debris from the device to resolve the problem.
(2) After using it for a long time, the generator cooling fan connection belt will gradually age, and then easily become broken or inelastic, resulting in abnormal blowing capacity. At this point it is necessary to replace the damaged belt. When replacing, all belts mustbe replaced together instead of just one.
(3) The coolant content is very low. It is necessary to check the factors causing the lack of cooling water. Check the tightness of the cooling water tank and each cooling water pipe. In the event of a leak, it must be repaired immediately. Then add enough coolant.
(4) The use of a coolant that does not meet the requirements causes the accumulation of scale, rust and other substances in the cooling water pipes, resulting in impedes the circulation of cooling water and causes an increase in water temperature. Coolant is usually water and antifreeze or water and anti-rust fluid. The pH value of water should be between 6.0 and 8.02_, and pure water is generally used. For cooling systemsent that have been seriously deposited and clogged, it is best to add 0.5 L of detergent for every 7 L of cooling system volume, mix it with clean water, start the machine and run it operate during 90 rain, circulate cooling water to clean. then use clean water to clean it Xian to prevent the cleaning agent remaining in the pipe from causing corrosion of the pipe.
1. This is usually caused by the dirty surface of the cooling water tank radiator of the 100 kW Cummins diesel generator set. A dusty environment can easily block the surface of the radiator, or when the device is working, debris may be sucked into the water tank by the cooling fan and block ventilation, resulting in poor heat dissipation. The problem can be solved by cleaning the surface of the water tank radiator with water.water or removing debris. It is noted that daily attention must be paid to maintaining the cleanliness of the computer room environment.
2. There is not enough coolant in the cooling water tank. It is necessary to check the reasons for the loss of cooling water. You can check for leaks in the cooling water tank and fuselage cooling water lines. If there are leaks, they must be repaired immediately. Then fill the coolant up to the normal level.
3. After prolonged use of the generator, the cooling fan belt will gradually age and become inelastic, or a certain belt will break, causing the cooling fan to lose its normal blowing capacity. At this point, the cooling fan belt needs to be replaced. During the remlocation, all of the belts must be replaced instead of just one.
4. Failure of the cooling water pump prevents cooling water from circulating and the water temperature rises. This is caused by wear of the internal gears and leaks after prolonged use of the water pump. This fault is also rare in emergency oil engines. At this time, you can only contact the manufacturer to repair or replace the water pump.
