燃氣發(fā)電機組的輸出功率一般都是按照線性負載設計的，雖然輸出功率也是視在功率伏安值，但它所指的無功功率是由正弦電流波形和正弦電壓波形之間的相位差造成的。以往的發(fā)電機負載主要是工頻機型UPS，這種UPS的輸入功率因數都不是正弦電流波形和正弦電壓波形之間的相位差，而是等效值。

The output power of the gas generator set is generally designed according to the linear load. Although the output power is also the apparent power volt ampere value, the reactive power it refers to is caused by the phase difference between the sinusoidal current waveform and the sinusoidal voltage waveform. In the past, the generator load was mainly power frequency ups. The input power factor of this UPS was not the phase difference between the sinusoidal current waveform and the sinusoidal voltage waveform, but the equivalent value.

換言之，工頻機型UPS的負載電流不是正弦波而是脈沖波，電壓在很多時候也不是純正的正弦波，而是失真程度不同的失真波。根據這種波形計算出來的功率因數雖然也是如O.7、O.8等，但含義卻大有不同，所以才有發(fā)電機的功率要為UPS功率數倍之說。該倍數的選擇根據在以后章節(jié)中有詳細說明。

In other words, the load current of power frequency UPS is not a sine wave but a pulse wave, and the voltage is not a pure sine wave in many cases, but a distortion wave with different degrees of distortion. Although the power factor calculated according to this waveform is also o.7, O 8, but the meaning is quite different, so there is a saying that the power of the generator should be several times that of the ups. The selection of this multiple will be described in detail in the following chapters.

此外燃氣發(fā)電機組的額定容量與額定功率的區(qū)別要了解到：

In addition, the difference between the rated capacity and rated power of the gas-fired generator set should be understood:

指代不同

Different references

1、額定功率：機械設備所能達到的大輸出功率，機械設備的實際輸出功率不會大于額定功率

1. Rated power: the large output power that the mechanical equipment can achieve, and the actual output power of the mechanical equipment will not be greater than the rated power

2、額定容量：銘牌上所標明的電機或電器在額定工作條件下能長期持續(xù)工作的容量。

2. Rated capacity: the capacity of the motor or electric appliance indicated on the nameplate that can work continuously for a long time under rated working conditions.、

特點不同

Different characteristics

1、額定功率：用電器正常工作時的功率。它的值為用電器的額定電壓乘以額定電流。若用電器的實際功率大于額定功率，則用電器可能會損壞；若實際功率小于額定功率，則用電器無法正常運行。

1. Rated power: the power of the electric appliance in normal operation. Its value is the rated voltage of the electric appliance multiplied by the rated current. If the actual power of the electric appliance is greater than the rated power, the electric appliance may be damaged; If the actual power is less than the rated power, the electric appliance cannot operate normally.

2、額定容量：主分接下視在功率的慣用值。如在變壓器上規(guī)定的容量就是額定容量，它是指分接開關位于主分接，是額定空載電壓、額定電流與相應的相系數的乘積。對三相變壓器而言，額定容量=額定空載線電壓×額定線電流,額定容量一般以kVA或MVA表示。

2. Rated capacity: the customary value of apparent power under main tap. For example, the capacity specified on the transformer nameplate is the rated capacity, which means that the tap changer is located at the main tap, and is the product of the rated no-load voltage, rated current and the corresponding phase coefficient. For three-phase transformer, rated capacity = rated no-load line voltage × Rated line current and rated capacity are generally expressed in KVA or MVA.

標準不同

Different standards

1、額定功率：在正常運行工作狀況下，動力設備的輸出功率或消耗能量的設備的輸入功率。常以“千瓦”為單位。也指工廠生產的機器在正常工作時所能達到的功率。即平常所說的某機器的功率，機器的額定功率是一定的。

1. Rated power: output power of power equipment or input power of energy consuming equipment under normal operating conditions. It is often expressed in kilowatts. It also refers to the power that the machine produced by the factory can reach during normal operation. That is to say, the power of a machine, the rated power of the machine is certain.

2、額定容量：規(guī)定的整個正常使用壽命期間，如30年，所能連續(xù)輸出大容量。而實際輸出容量為有負載時的電壓（感性負載時，負載時電壓小于額定空載電壓）、額定電流與相應系數的乘積。

2. Rated capacity: it can continuously output large capacity during the specified normal service life, such as 30 years. The actual output capacity is the product of the voltage under load (under inductive load, the voltage under load is less than the rated no-load voltage), the rated current and the corresponding coefficient.
