△KUC755AE106 3BHB005243R01 06 Excitation controller module
(1) Measurement and comparison unit. Measure the generator voltage signal, convert it into DC voltage signal proportionally, compare with the DC voltage, and send the motor voltage deviation signal. For running side by side
To distribute the power of each unit reasonably and stably, the adjustment unit should be set up.
(2) Comprehensive amplification unit. It is composed of a comprehensive amplification link, a proportional integration link and an adaptor link. The integrated amplification link generates a variety of basic measurement outputs, feedbacks and auxiliary limits to absorb stable and stable
All kinds of DC signals of compensation reaction are amplified comprehensively and output to the proportional integration link. The proportional integration link is processed and output according to the predetermined regulation law. The adaptor link amplifies the signal voltage
The phase shift control signal voltage controls the excitation voltage.
(3) Phase shift trigger unit. The output signal voltage of the integrated amplifier unit is accepted, and the trigger control Angle of the thyristor is changed to control the excitation voltage.
(4) Regulated power supply. The input AC and DC power supply is converted into the voltage stable power supply required by the excitation regulator. The input AC and DC power supply should be able to switch automatically in a timely manner.
(5) Various other auxiliary function units:
1) Maximum excitation current limiter. The total current value of the output of the thyristor rectifier bridge is limited below the given excitation ceiling current.
2) Excitation overcurrent limiter. When the strong excitation or excitation overcurrent reaches the allowable time, the excitation current is reduced to the long-term allowable maximum value.
3) Underexcitation limiter. According to the need of generator and power system stability calculation, the minimum output current of thyristor rectifier bridge is limited to the given value corresponding to the active power.
4) Voltage/frequency limiter. It is mainly used during no-load operation when the generator is disconnected from the power grid to prevent the unit from running below the power frequency due to the governor failure, resulting in false strong excitation and over-excitation failure.
(6) Manual unit. In the early stage, the excitation was adjusted manually by open-loop method, and later the closed-loop regulation method with the excitation current as the signal source was adopted.
(7) Tracking unit. At each moment when the regulator is adjusted in "automatic mode" to the generator terminal voltage for the signal closure loop, the tracking unit automatically closely tracks the excitation current signal of the manual unit corresponding to the preceding
Voltage signal "to ensure that when the" automatic "switch to the" manual "type, there is no large fluctuations in excitation. When the regulator "automatic" regulation type has a - master - standby dual channel, it needs to be protected
The standby channel automatically tracks the signal of the primary channel.
(8) Imbalance (pulse disappearance) protection. Monitor the main channel and automatically switch to the standby channel when the main channel pulse disappears or becomes abnormal.
