Product introduction
As a power supply equipment, weifang generating set should provide electrical energy that meets the requirements. The electrical performance index is not only the standard to measure the power supply quality of the unit, but also the main basis for the correct use and maintenance of the unit. Therefore, for use and maintenance personnel, must be familiar with the unit's main electrical performance indicators. The main electrical performance indexes of diesel generator include steady state index and dynamic index.
(1) steady-state indicators
The electrical performance index of a generator set when it operates stably under certain load is called steady-state index.
1 - rating
For a generator set, rating refers to the data marked on the unit's nameplate.
2. Adjustment range of unloaded voltage Uz
When the unit is running stably, its no-load voltage should be adjusted within a certain range, because there is a difference between the unit and the electrical equipment. When the cable voltage drop is fixed, the unit should ensure that the output cable terminal still has normal working voltage under certain load.
Generally, the no-load voltage range is 95% of the rated voltage. 10%. For example, when the rated voltage of a unit is 400 V, its no-load voltage adjustment range is 380, 420 V. The voltage setting device determines the most? < minimum) voltage, V.
3. Voltage thermal offset
When the ambient temperature and the temperature of the generator itself rise, the magnetic permeability of the generator core falls, the direct current of the winding, plus, the circuit element parameters change, thus causing the change of the generator output voltage. This phenomenon is called voltage thermal shift. Usually, you raise the temperature, right? The ratio of voltage change to the rated voltage to the total voltage change of the unit indicates that the unit's voltage thermo-displacement is generally not allowed to exceed 2%
4. Voltage waveform distortion rate
The ideal waveform of output voltage of generator set should be sinusoidal wave, but its actual waveform is not real sinusoidal wave. It contains both fundamental wave and high harmonics of three or more times, especially the generator set with three-time harmonic excitation. The percentage of the root mean square value and the effective value of the fundamental wave of each harmonic is called the voltage wave distortion rate. Generally, the unloaded rated voltage waveform distortion rate of generator sets should be less than 10%. The distortion rate of voltage waveform is too large, which will make the generator hot seriously, and the temperature rise will damage the insulation of the generator, which will affect the normal working performance of the generator.
5. Voltage steady-state adjustment rate
The voltage steady-state adjustment rate refers to the deviation degree of the stable voltage of the unit after the load changes relative to the rated voltage of the unit when the unit is no load, which is expressed as a percentage. That is the unit output voltage and rated voltage difference and rated voltage ratio.
Type in & have spent U & ndash; Rated voltage, V;
Maximum (minimum) stable voltage for U1 generator set after load gradient, V.
The steady-state voltage adjustment rate is an important index to measure the stability of the generator terminal voltage. The smaller the steady-state voltage adjustment rate is, the smaller the influence of load change on the unit terminal voltage is, and the higher the stability of the unit terminal voltage is.
The voltage steady-state adjustment rate varies under different loads. Under inductive load, the stable voltage after load change is lower than the no-load rated voltage; Under capacitive load, the stable voltage after load change is higher than the no-load rated voltage. However, the deviation relative to the no-load rated voltage depends on the adjustment ability of the excitation regulator. The stronger the adjustment ability, the smaller the deviation value, the smaller the voltage steady-state adjustment rate, and the more stable the terminal voltage of the generator.
6. Frequency steady-state adjustment rate
Frequency steady-state adjustment rate refers to the percentage of the difference between the unit's stable frequency and the rated frequency before and after the load changes.
In the formula, f 1 rated frequency, Hz.
Formula one? Maximum stable frequency after load gradient (minimum >,
Steady-state frequency of F2 - one load as rating, Hz.
The smaller the frequency steady-state adjustment rate is, the more stable the frequency is when the load changes. The frequency steady-state regulation rate is related to the speed regulation energy of the engine. The stronger the regulation ability of the governor, the more stable the frequency when the load changes.
7. Voltage volatility
When the load is constant, the generator excitation system is unstable and the engine speed fluctuates. The outgoing voltage will also fluctuate. Therefore, the regulating performance of generator excitation regulator and engine governor can be improved accordingly, which can reduce the fluctuation of unit voltage. In the formula *100% of voltage fluctuation 'rate, UBmax and UBmin are the maximum and minimum voltage values in the same observation time.
Frequency volatility
When the load is constant, the frequency of the unit will fluctuate due to internal reasons. The fluctuation of unit frequency is mainly caused by the instability of engine governor and uneven rotation of engine crankshaft. Therefore, the performance of the engine and its governor can be improved correspondingly to reduce the frequency fluctuation of the unit.
