Key Parameters of Diesel Generator Sets

For those with basic knowledge of diesel generator sets, it is known that the key factors determining their performance include rated power, rated voltage, rated current, etc. When purchasing a diesel generator set, special attention should be paid to the rated power of the diesel engine.

Generally, when referring to power supply power, we mean the rated power. Therefore, when selecting a diesel generator set, it is crucial to focus on the rated power rather than the standby power. Some unscrupulous sellers fail to clarify whether the power mentioned is standby power or rated power. Standby power is the maximum power, not the rated power, and it should be noted that the maximum power is the limit of the unit. Therefore, it is recommended to choose manufacturers with a good reputation, as reputable brands usually clearly indicate the rated power. All references to diesel generator set power in the following text refer to rated power.

Rated Parameters for Measuring Diesel Generator Set Performance

(1)Rated Power (PE): Refers to the maximum active power that a diesel generator set can output under rated operating conditions, with units of kilowatts (KW) or megawatts (MW).

(2)Rated Power Factor (cosφ): Refers to the power factor of the generator during rated operation.

(3)Rated Voltage (UE): Refers to the line voltage of the diesel generator set during normal operation, with units of volts (V) or kilovolts (kV).

(4)Rated Current (IE): Refers to the line current of the diesel generator set when operating in the rated state, with units of amperes (A) or kiloamperes (KA).

(5)Rated Speed (NC): The speed required for the diesel generator set to maintain the alternating current frequency at50Hz, with units of revolutions per minute (r/min).

(6)Rated Efficiency: Refers to the efficiency of the diesel generator set when operating in the rated state.

(7)Rated Frequency (FE): The rated frequency in China is specified as50Hz.

(8) Rated Temperature Rise: The allowable temperature increase of the stator winding and rotor winding of the diesel generator set during operation compared to the ambient temperature. In China, the ambient temperature is calculated at40℃.
