Various environmental performance indicators related to engine generator set
As environmental problems continue to be bad, environmental protection has become a hot topic in advanced society. With the implementation of the most stringent environmental protection law, many industries have been affected by it, setting off a wave of environmental protection innovation. For the diesel engine generator set industry, the same is true. Interoperability is here to introduce the various environmental performance indicators of engine diesel generator sets.
1. The noise sound pressure level is usually measured at a distance of 7m from the unit, the normal unit is not more than 100dB(A), and the lowest of the low noise unit is 56dB(A).
2. The vibration amplitude is generally not more than 5mm.
3. After the exhaust smoke is higher than 40℃, there should be no obvious smoke and no obvious carbon particles.
4. Radio interference: There should be measures to suppress radio interference, and its interference value should comply with national standards.
To realize the environmental protection of dg genset generator sets, technology is the only means. Only by innovating technology to improve performance, on the other hand, continuously improving industry standards and standardizing production, can we achieve comprehensive environmental protection in the entire field of diesel generator sets.
The technical performance indicators of diesel generators are the main basis for measuring the engine genset supply quality and economic indicators of the unit. Its main technical performance usually refers to the performance that should be achieved when the power genset factor of the unit is from 0.8 to 1.0, and the three-phase symmetrical load is gradually or suddenly changed from 0 to 100% or 100% to 0 rated value.
One, stable voltage adjustment rate δu
In the formula, U1——Maximum value (or minimum value) of temperature power supply after load change; U——No-load setting voltage value.
The δu of category Ⅰ～Ⅲ units is ±(1～3)%; the δu of category IV units should not exceed ±5%.
2. Steady-state frequency adjustment rate δf
where f1——the maximum value (or minimum value) of the steady-state frequency after the load gradually changes;
F2——Frequency at rated load;
F——Rated frequency.
The δf of category Ⅰ～Ⅲ units is 0.5%～3%; the δf of category IV units does not exceed 5%.
3. Voltage stabilization time
The time required for the voltage to start to stabilize when the load changes suddenly, usually measured with an oscilloscope.
The voltage stabilization time of category Ⅰ～Ⅲ units is 0.5~1s; the voltage stabilization time of category IV units is 3s.
4. frequency stabilization time
The time from when the load changes suddenly to when the frequency starts to stabilize is usually measured with an oscilloscope.
The frequency stabilization time of TypeⅠ～Ⅲ units is 2～5s; the frequency stabilization time of Type IV units is 7s.
5. No-load voltage setting range
The set voltage of the unit should be able to adjust and work stably within the range of 95%～105% of the rated value. For example, for a unit with a rated voltage of 400 kva generator fuel consumption, its no-load voltage can be adjusted between 380V and 420V.
6.Stability of operating voltage under three-phase asymmetric load
When the unit is operated under a three-phase asymmetrical load, if the current of each phase does not exceed the rated value, and the difference between the currents of each phase does not exceed 25% of the rated value, the difference between the line voltage and the average value of the three-phase voltage should not More than 5% of the average value of the three-phase line voltage.
7. the parallel performance of the unit
Two three-camera groups with identical specifications and models should be able to operate in parallel within the range of 20% to 100% of the rated power under the rated power factor. In order to improve the active power and reactive power, the reasonable distribution accuracy and the stability of operation, the diesel engine governor in the unit is required to have a device that can adjust the steady-state speed regulation within the range of 2% to 5%. The voltage regulating device in the control box (screen) can adjust the steady-state voltage adjustment rate within 5%.

The electrical performance index of a diesel generator set is not only a standard for measuring the quality of the power supply of the set, but also the main basis for the correct use and maintenance of the set. The electrical performance index of a diesel generator set when it runs stably under a certain load is called a steady-state index, and its value is generally displayed on the nameplate of the unit. Diesel generator sets are very widely used in our daily use. Many customers do not know some professional terms when they buy them. Bidirection Power Technology will continue to introduce you to the explanation of related terms for diesel generator sets in the next period of time. Let me introduce the meaning of the steady-state index ratings of dg diesel generator sets, hoping to help you better understand diesel generator sets.
The electrical performance index of diesel generator set is a standard to measure the power supply quality of diesel generator set, and it is also the main basis for proper use and maintenance of diesel generator set. The electrical performance index of a diesel generator set running stably under a certain load is called a steady-state index, and its value is usually displayed on the nameplate of the diesel generator set. The voltage frequency of the diesel generator set running at the rated speed is called the rated frequency.
In short, Bidirection Power is here to remind everyone that since all equipment is set according to the rated frequency of the system, the decrease in the quality of the frequency of the generator set will affect all walks of life. When the frequency is too low, the entire system will even collapse.
The above is the relevant content of the environmental performance indicators of diesel generator sets shared by the dg set manufacturer. If you need to know more about genset engine sets, you can come to us and we will patiently answer for you.
