TRIM: reactive power regulation at the same time;

D88尊龙OVER EXC:過勵磁保護調節;

D88尊龙OVER EXC: over excitation protection regulation;

STAB:穩定 調節

STAB: stable regulation

D88尊龙A、 VOL:電壓調節 作用:電壓調整 如輸出電壓不符,順時針旋轉電壓調節電位器,輸出電壓升高; 反之則反。

D88尊龙A, VOL: voltage regulation: voltage regulation such as output voltage does not match, clockwise rotation voltage adjustment potentiometer, output voltage rise; vice versa.

B、DROOP:并機時的無功調節 作用:調節電流補償壓降

B and DROOP: reactive power regulation function: regulating current compensation voltage drop.

D88尊龙C、UF:低頻保護調節 作用:起低頻保護

C, UF: low frequency protection and regulation: low frequency protection

D、TRIM:并機時的無功調節

D, TRIM: reactive power regulation at parallel time

作用:優化電壓修正靈敏度.

Function: optimize voltage correction sensitivity.

D88尊龙1、根據發電機負荷的變化相應的調節勵磁電流,以維持機端電壓為給定值;

D88尊龙1, adjust the excitation current according to the change of generator load to maintain the terminal voltage as a given value.

D88尊龙2、控制并列運行各發電機間無功功率分配;

D88尊龙2, control the parallel operation of reactive power distribution among generators.

D88尊龙3、提高發電機并列運行的靜態穩定性;

3, improve the static stability of generator parallel operation.

4、提高發電機并列運行的暫態穩定性;

D88尊龙4, improve the transient stability of generator parallel operation.

5、在發電機內部出現故障時,進行滅磁,以減小故障損失程度;

5, in the generator internal fault occurs, de excitation, in order to reduce the degree of failure loss;

6、根據運行要求對發電機實行大勵磁限制及小勵磁限制等。

D88尊龙6, according to the operation requirements, the generator excitation limits and minimum excitation limits are implemented.

D88尊龙E、OVER EXC:過勵磁保護調節 作用:過流減勵 使發電機在額定功率下,逆時旋轉勵磁脫扣電位器,使指示二極 管發光,再順時旋轉約5度即可。

E, OVER EXC: over excitation protection regulation: over current reducing excitation makes the generator under the rated power, reverse rotation excitation to remove the potentiometer, so that the indicator diode light, and then rotate about 5 degrees.

D88尊龙F、STAB:穩定調節 作用:調整穩定度.

F and STAB: stabilizing effect: adjusting stability.
