An overview of the
WLT - 03 using a new generation of microcomputer excitation regulator GEX - 2000. It has the perfect regulation, control and limit protection function, and the computing speed, resistance to electromagnetic interference, reliability and ease of use has the very big enhancement. From in1 GEX - 2000 is suitable for all manner of thyristor excitation to self shunt excitation, is the ideal of modern medium and large synchronous generator excitation control device.
The main technical parameters
1. The CPU type: 32 bit high speed DSP chip
2. The pressure regulating range: 5% ~ 130%
3. The voltage regulation accuracy: < 0.5%
4. The phase shifting range: 0 ~ 150 degrees, upper and lower limit value can be set up procedures
5. The poor: software reactive power difference, plus or minus size choose differential is plus or minus 1%.
6. Frequency: the frequency of each 1% change, does not change size generator terminal voltage rating of plus or minus 0.25%.
7. Setting adjustment speed: programmable, meet is not more than 1% per second, no less than 0.3% per second.
8. In the case of no-load voltage rating, when the generator of a given order number plus or minus 10%, the generator voltage overshoot step amount of less than 30%, oscillation frequency is less than 2 times, adjust the time less than 5 seconds.
9. When the generator zero up the booster, the machine terminal voltage overshoot amount does not exceed 10% of the rated voltage, oscillation frequency is less than 2 times, adjust the time less than 5 seconds
10. Work style: double ark all flow (3 in1 systems), the main standby (self-excitation method)
11. Excitation system installed power system stabilizer (PSS), the effective frequency range from 0.1 to 0.1 Hz.. At the same time, set up the necessary protection and control circuits.
12 years of excitation system is forced to quit than not greater than 0.05%
13. The excitation system of national standard severe electromagnetic interference test for level 3 standard, at the level of disturbance should not occur misadjustment, disorder, misoperation, refused to move, and so on and so forth.
