Performance Level National Standard GB diesel generator set / T2820 1-1997 "Reciprocating internal combustion engine driven alternator group" Part I: Application, ratings and performance in Article 7 of the diesel generator set provides four properties. (1) G1-level performance requirements apply only provides the basic parameters of the voltage and frequency of the connected load. Mainly as a general purpose, such as lighting and other simple electrical load. (2) G2-level performance requirements applicable to utility power system voltage characteristics and have the same required load. When its load changes, however, may be allowed to have temporary voltage and frequency deviation. Such as lighting systems, such as pumps and fans. (3) G3-level performance requirements apply to the right frequency, voltage and waveform characteristics, there are strict requirements for connecting devices. Such as radio communications and thyristor controlled rectifier load. (4) G4 level performance requirements apply to the frequency, voltage and waveform characteristics are particularly stringent requirements of the load. A data processing device or meter grate system. Oil Turbine Generator and compare East diesel manufacturers, has the following characteristics: ① volume per unit of output is small, light weight, simple system, and more generally for the overall package. Therefore, diesel power plant construction speed. ② high thermal efficiency diesel power generation, and part load or light load, change the fuel consumption per unit of output is unlikely. ③ start diesel generator sets, with load and downtime is short, it can start at any time, is more suitable for emergency power supply. ④ diesel generator operation and maintenance than the turbine generator set is simple and convenient. But East diesel price quotes, diesel generator sets are also some disadvantages: ① only use liquid fuel, fuel more expensive, so the higher energy costs. ② East wear large diesel engine, a shorter life span, more frequent maintenance. Operational stability and overload capacity means worse than steam power. Less vibration and noise of the big East diesel unit suppliers, workers operating conditions ③ running. Pole surface ④ generator brake coil must be provided in order to facilitate the starting unit stops. "(GB- 3096- 82) in the second-class district standards, the field test day ≤55dB (A), in the evening ≤45dB (A) achieved the goal of eliminating noise pollution.
