Safety operation procedures for generators

First, the operation of the engine part of the generator powered by diesel engine shall be carried out in accordance with the relevant provisions of the internal combustion engine.

Second, before starting the generator, you must carefully check whether the wiring of each part is correct, whether the connecting parts are firm, whether the brush is normal, whether the pressure meets the requirements and whether the grounding wire is in good condition.

Third, before starting, put the resistance value of the excitation rheostat at the maximum position, turn off the output switch, and the generator set with clutch should disengage the clutch. Start the diesel engine with no load first, and then start the generator after the generator runs smoothly.

Four, after the generator starts running, should always pay attention to the presence of mechanical noise, abnormal vibration, and so on and so forth. After confirming that the situation is normal, adjust the generator to the rated speed, adjust the voltage to the rated value, and then turn off the output switch to supply power to the outside. The load should be gradually increased to achieve three-phase balance.

Seven, did you receive it? Are you ready for parallel connection? Signal, based on the whole device, adjust the speed of the diesel engine and turn it on at the synchronous moment.

Eight, generators running in parallel should adjust the load reasonably and distribute the active power and reactive power of each generator in a balanced way. Active power is regulated by diesel engine throttle, and reactive power is regulated by excitation.

Nine, the running generator should pay close attention to the engine sound, observe all kinds of instruments.

Indicates whether it is within the normal range. Check whether the running part is normal and the generator temperature rise is too high. And make a running record.

Ten, when parking, first reduce the load, make the excitation rheostat reply, minimize the voltage, and then cut off the switch in sequence, and finally stop the diesel engine running.

1 1. If a diesel engine running in parallel needs to be stopped due to load drop, the load of a generator that needs to be stopped should be transferred to the generator that continues to run, and then it should be stopped by a single generator. If full shutdown is required, the load should be cut off first, and then the single generator should be shut down.

Seventeen, the computer room should be equipped with necessary fire fighting equipment, fire accident should immediately stop sending, turn off the generator, and put out the fire with carbon dioxide or carbon tetrachloride fire extinguisher.

Noise reduction treatment of generator room

When the diesel generator set is running, it usually produces noise of 95 ~ 128 b(a). If necessary noise reduction measures are not taken, the noise generated by unit operation will cause serious damage to the surrounding environment. In order to protect and improve environmental quality, noise must be controlled.

The main noise sources of diesel generator sets are all generated by diesel engines, including exhaust noise, mechanical noise and combustion noise, cooling fan and exhaust noise, intake noise, generator noise, noise generated by foundation vibration transmission, etc.

(1) Exhaust noise. Exhaust noise is a kind of pulsating airflow noise with high temperature and high speed, which has the largest energy in engine noise, and its noise can reach more than 100db, and it is the most important part of the total engine noise. The exhaust noise generated when the generator is working is directly discharged through the simple exhaust pipe (the original exhaust pipe of the generator set). With the increase of airflow speed, the noise frequency also increases obviously, which has a serious impact on the life and work of nearby residents.

(2) Mechanical noise and combustion noise. Mechanical noise is mainly caused by the vibration or mutual impact of engine moving parts caused by periodic changes of gas pressure and inertia force. It has the characteristics of long noise propagation and small attenuation. Combustion noise is the structural vibration and noise produced by diesel during combustion.

③ Cooling fan and exhaust noise. The fan noise of the unit consists of eddy current noise, rotating noise and mechanical noise. Exhaust noise, airflow noise, fan noise and mechanical noise will spread out through the exhaust passage, thus causing noise pollution to the environment.

(4) Intake noise. The function of the air inlet is to ensure the normal operation of the engine and create good heat dissipation conditions for the unit itself. The air inlet channel of the unit must be able to make air enter the machine room smoothly, but at the same time, the mechanical noise and airflow noise of the unit will also radiate to the outside of the machine room through this air inlet channel.

(5) Propagation noise of foundation vibration. The strong mechanical vibration of diesel engine can spread to all parts of the outdoor through the foundation, and then radiate noise through the ground.

The principle of noise reduction in diesel generator room is to reduce the noise of intake and exhaust channels and exhaust systems by using efficient sound absorption materials and noise reduction and silencing devices under the premise of ensuring the ventilation conditions of diesel generator set, so that the noise emission can reach the national standard (85db(a)).

The most fundamental way to reduce generator noise is to start with the sound source and adopt some conventional noise reduction technologies; Such as muffler, sound insulation, sound absorption and vibration isolation are the most effective methods.

(1) Reduce exhaust noise. Exhaust noise is the main noise source of the unit, which is characterized by high noise level, fast exhaust speed and difficult control. The exhaust noise can generally be reduced by 40-60db(a) by using a compound muffler with special impedance.

(2) Reduce the noise of axial flow fan. Two problems must be considered when reducing the noise of the cooling fan of the generator set. One is the allowable pressure loss of the exhaust port. The second is the required noise reduction. In view of the above two points, you can choose the resistor muffler.

(3) Sound insulation and sound absorption treatment of the machine room and vibration isolation of the unit

1) Sound insulation in the machine room. After the exhaust noise and cooling fan noise are reduced, the remaining main noise sources are diesel engine mechanical noise and combustion noise. The method adopted is to remove all the windows outside the observation window from the inner wall connected to the observation room, all the holes should be sealed tightly, and the sound insulation capacity of the brick wall should be greater than 40db(a). The computer room adopts fire-proof and sound-proof doors and windows.

2) Air intake and exhaust. After the sound insulation treatment of the computer room, the ventilation and heat dissipation of the computer room should be solved. The air inlet shall be arranged in the same straight line with the generator set and the air outlet. The air inlet shall be equipped with a resistor muffler. Because the pressure loss of the air inlet is also within the allowable range, the air flow in and out of the machine room can be naturally balanced, and the ventilation and heat dissipation effect is obvious.

3) Sound absorption treatment. The five walls in the machine room except the ground can be used as sound absorption treatment, and the perforated plate vibration sound absorption structure is adopted according to the frequency spectrum characteristics of the generator set.

4) Indoor air communication and good sound insulation in the machine room will prevent air convection in the machine room when the closed water-cooled generator set is shut down, and the high temperature in the machine room cannot be reduced in time. This problem can be solved by using low noise axial flow fan and resistive muffler.

5) Vibration isolation of the unit. Before the installation of the generator set, vibration isolation shall be carried out in strict accordance with the relevant information provided by the manufacturer to avoid the long-distance transmission of structural sound, which will continuously radiate air sound during the transmission process, so that the noise level at the factory boundary cannot meet the standard. For the existing generator set that needs to be treated because of exceeding the standard, the vibration of the ground near the generator set must be measured. If the vibration is obvious, the generator set should be isolated first.

After effectively reducing noise, in order to make the environment of computer room more beautiful and practical, microporous aluminum-plastic perforated plates are usually decorated on the sound-absorbing layers of walls and ceilings, and the lighting system is reasonably configured.
