I. Overview
XES-02 excitation controller is a 32-bit all-digital excitation controller independently developed by our company. This controller is a high-end excitation controller. It can use either 32-bit ARM as the main control chip or 32-bit DSP. The main control chip adopts full Chinese LCD display, and all parameter settings are digitized. One controller can be used to form a single microcomputer excitation device, or two controllers can be used to form a dual microcomputer excitation device. The entire controller consists of a 6-layer circuit board and LCD display, which is simple, convenient and powerful. It is suitable for the excitation devices of various types of generator sets below 100MW, and is the first choice for the supporting production of excitation manufacturers, generator manufacturers, automation monitoring manufacturers and power station excitation transformation.

Main performance parameter
Machine terminal voltage measurement UF: rated value of secondary side of voltage transformer 100V
Stator current measurement IF: 5A input or 1A input rating
Rotor current measurement IL: Hall current sensor measures 0 ~ 100mA
Trigger pulse frequency: 10KHz
Analog input channels: 16
Digital input: 40 channels
Digital output: 40 channels
Auto / manual adjustment range: (10 ~ 130)% of rated value
Start-up: overshoot is less than 1% of rated value, start-up time is less than 2.5 seconds, and the number of oscillations is less than 1
Adjustment rate: software reactive power adjustment ± 15%
Voltage regulation accuracy: not more than ± 0.5%
Phase shift range of thyristor: 5 ~ 145 °
Thyristor control angle resolution: 1/20000
The excitation system can meet the manual and automatic quasi-synchronous grid-connected power generation of the unit
Guaranteed long-term operation at 110% excitation current
1% change in the operating frequency of the unit and no more than 0.1% change in the rated unit voltage
When the terminal voltage drops to 80% of the rated value, it provides more than twice the strong excitation current for a duration of not less than 20 seconds
Excitation system voltage response time: rise time is less than 0.08 seconds, fall time is less than 0.15 seconds
Voltage response ratio is not less than 2 units / second
Regulation accuracy of automatic excitation regulator is less than 0.2% of rated voltage
The normal excitation method is residual voltage excitation. When the residual voltage is 2% of the rated voltage, it can be excited. When there is no residual voltage, it is automatically excited by microcomputer detection and control without manual intervention. The capacity of automatic excitation is 1kVA, no overshoot and oscillation
After the generator suddenly dumps the rated active and rated reactive loads, the voltage overshoot at the generator end is not greater than 10% of the rated value, the number of oscillations does not exceed 3 times, and the adjustment time is not greater than 5 seconds
Excitation PT is equipped with disconnection detection, automatic switching and protection, and concurrent signals
Rotor overvoltage protection, concurrent signal
Fan stop wind protection, concurrent signal
Power bridge rectification fault protection, concurrent signal
Under-excitation limit function
Strong excitation limit value function and strong excitation inverse time function
Remote control and local control functions
Regulation accuracy of automatic excitation regulator is better than 0.1% of rated voltage
Can communicate with host computer by RS485 or Ethernet
Can use switch value as interface
Voltage response ratio is not less than 2 units / second
