发电机组额定容量认识的相关信息

返回 2022.08.11 来源:http://www.huannengpower.com
燃气发电机组的输出功率一般都是按照线性负载设计的,虽然输出功率也是视在功率伏安值,但它所指的无功功率是由正弦电流波形和正弦电压波形之间的相位差造成的。以往的发电机负载主要是工频机型UPS,这种UPS的输入功率因数都不是正弦电流波形和正弦电压波形之间的相位差,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.
换言之,工频机型UPS的负载电流不是正弦波而是脉冲波,电压在很多时候也不是纯正的正弦波,而是失真程度不同的失真波。根据这种波形计算出来的功率因数虽然也是如O.7、O.8等,但含义却大有不同,所以才有发电机的功率要为UPS功率数倍之说。该倍数的选择根据在以后章节中有详细说明。
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.

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

1、额定功率:用电器正常工作时的功率。它的值为用电器的额定电压乘以额定电流。若用电器的实际功率大于额定功率,则用电器可能会损坏;若实际功率小于额定功率,则用电器无法正常运行。
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、额定容量:主分接下视在功率的惯用值。如在变压器上规定的容量就是额定容量,它是指分接开关位于主分接,是额定空载电压、额定电流与相应的相系数的乘积。对三相变压器而言,额定容量=额定空载线电压×额定线电流,额定容量一般以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.

1、额定功率:在正常运行工作状况下,动力设备的输出功率或消耗能量的设备的输入功率。常以“千瓦”为单位。也指工厂生产的机器在正常工作时所能达到的功率。即平常所说的某机器的功率,机器的额定功率是一定的。
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、额定容量:规定的整个正常使用寿命期间,如30年,所能连续输出大容量。而实际输出容量为有负载时的电压(感性负载时,负载时电压小于额定空载电压)、额定电流与相应系数的乘积。
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.
