The purpose of static working characteristics of comprehensive excitation regulator

The purpose of static operation characteristics of synthetic excitation regulator is as follows:

1, static characteristics of valve train.

2. Stroke relation curve of synchronizer and oil motor.

3. The relationship curve between the stroke of oil motor and the opening of each control valve.

4. Adjust the opening overlap of the air valve.

In addition, on-load test can also check whether the regulating system is stable at each load point. Set the static characteristic test results, and summarize the empty load and on-load test records. If the steam parameters change greatly during the test, the power should be corrected, and then the static characteristic curve of the induction mechanism should be drawn according to the data of the empty load test.

Drive the static characteristic curve of the amplification mechanism, draw the static characteristic curve of the valve train from the data of the on-load test, then draw the static characteristic curve of the regulating system on the four-quadrant coordinate diagram, and calculate the speed change rate and hysteresis rate of the regulating system from the curve.

Synchronizer working range test

It is mainly to check whether the steam turbine can maintain idling, whether it can be integrated into and separated from the power grid at a lower power grid frequency, and check the working range after the synchronizer is set. For the system without auxiliary spring synchronizer, the static characteristic line of the induction mechanism can also be measured. ?

No-load acceleration and deceleration test: it mainly measures the static characteristic lines of induction mechanism and transmission amplification mechanism. When testing, put the synchronizer in the middle position and the upper limit position respectively (the lower limit position has little practical significance and is unnecessary).
