Household diesel generators.
Power generation cannot be connected to the grid. Because private power generation equipment needs to apply to the relevant departments if it wants to be connected to the grid, the power supply company will send someone to test and check whether it meets the grid connection requirements. Generally speaking, domestic diesel generators are not eligible for grid connection.
Diesel generator is a small power generation equipment, which refers to the diesel engine that uses diesel as fuel.
A power machine that drives a generator to generate electricity for the prime mover. The whole unit is generally composed of diesel engine, generator, control box, fuel tank, starting and control battery, protection device, emergency cabinet and other components.

The electricity generated by self-provided generators should be connected to the public power grid, not just if you want to, which involves special approval and technical problems.
However, if it's for personal use, it's simpler. If there is no requirement for power supply immediately after a power outage, it can be solved by using double-headed switches, busbars and other methods: disconnect the incoming line of the public power grid and replace it with the power supply of its own generator.
If you need automatic power generation and power supply in case of power failure, you need special equipment, which is a little expensive, and it is used by general hospitals, communications, and key departments, and you can't use it at home.
-
In China, except for a few special power sources such as power plant security power supply, which can apply for grid connection, general diesel generator sets are not allowed to be connected to the grid, but they can be connected to the grid. According to the situation as you mentioned, you can consider purchasing ATS (dual power automatic transfer switch) to solve the problem, which can realize one main and one backup power; That is, when the mains power is off, the unit will automatically start and realize load.
-
Diesel generators are not allowed to be connected to the grid in use, and an ATS (dual power automatic transfer switch) should be assembled to connect with the mains, and then the double-head switch can be used to achieve the above requirements.

3.When connected to the grid, it is necessary to use a professional grid-connected controller or synchronization controller to realize the synchronous operation of the two generator sets, and ensure that their output power is synchronized with the public power grid. 4.
Once connected to the grid, the two generator sets need to be monitored and adjusted to ensure that their output quality meets the requirements of the public grid.

Summary. Pro, two diesel generator sets can be connected to the grid, which can increase the overall power supply capacity and improve the reliability of the power system. The following are the general steps to connect two diesel generator sets to the grid:
1.Determine the grid-connected mode and control mode. To connect each generator set to the grid, the grid-connected mode and control mode need to be determined.
Generally speaking, the mode of grid-connected parallel operation is usually adopted, that is, the two diesel generator sets operate independently but share the load. 2.Set the control parameters.
Set control parameters such as voltage, frequency, regulator, etc., to ensure that the output power of the two diesel generator sets matches the demand of the power grid. 3.Check the protective device.
Check the protection system of the diesel generator set, such as overcurrent, overload, underfrequency, overfrequency, etc., to ensure the safety of grid-connected operation. 4.Merge into the load.
Two diesel generator sets are incorporated into the load separately and the voltage, frequency and output power are measured. By adjusting the control parameters and control system, it is ensured that the load is reasonably shared between the two diesel generator sets and the load. It should be noted that the grid-connected operation of diesel generator sets requires professional technicians to operate to ensure system safety and stability.
In addition, in the grid-connected operation, it is necessary to follow the requirements of national power industry standards and safety specifications, and operate in strict accordance with the operating procedures.

The grid connection of diesel generator sets needs to meet certain technical requirements to ensure the safety and stability of the process of merging and dispersing the grid. It is recommended that you consult a professional power generation engineer or electrical engineer before connecting to the grid, and follow these steps:
1. Confirm whether the parameters of the two diesel generators are the same, such as voltage, frequency, power, etc.;
2. Configure synchronizer to ensure that the voltage, frequency and phase output of the two diesel generators are in the synchronization range;
3. Connect two diesel generator sets and realize grid connection through synchronizer;
4. After synchronization, check and confirm whether the voltage, frequency and phase output of the two diesel generator sets are consistent, and whether they meet the requirements of the power grid;
5. If there is a change in grid voltage, frequency or phase, the synchronizer should be able to automatically adjust to keep the synchronization of the two gensets.
It should be noted that before the diesel generator set is connected to the grid, it must ensure that its electrical number and physical connection meet the requirements, and select the appropriate synchronizer for control. In addition, it is recommended that you be cautious in the operation of the grid, because the grid-connected operation requires high technical operation ability and experience, so as to ensure the safety of your personal and equipment.

<> during the grid-connected test of diesel power generation and good consumption engine, the generator will first synchronize with the grid by adjusting the frequency, voltage and phase of the generator. Once the synchronization state is reached, the generator starts to supply power to the grid. This means that the generator will adjust its output to meet the needs of the grid and deliver power to the grid.
During the test, the output power of the generator will be adjusted according to the load change of the grid to maintain the stable operation of the grid. At the same time, the power grid will also monitor the operating status of the generator to ensure that the generator can work normally during the grid connection. All in all, in the process of grid connection test of the diesel generator, the generator will send power to the grid to use the power supply network

Hello, no, during the grid-connected test of the diesel generator, according to the normal operation process, the electric energy will not be sent back to the grid. The grid-connected test is mainly to verify the operation status, stability and normal connection of the diesel generator to the power grid. During the test, the generator will provide the shielded energy to supply the test load, but will not send the excess energy back to the grid.
In the grid-connected test, corresponding protection devices and control systems are usually set up to ensure the safe and reliable connection between the generator and the power grid. If the output capacity of the generator is greater than the demand of the test load, the excess electrical energy is absorbed by the test load and will not be returned to the grid. However, it should be made clear that the grid-connected test is a very professional operation that requires strict adherence to the relevant safety norms and operating procedures.
