HONEYWELL TC-CCR014卡件模塊,TC-CCR014使用產品
在調整控制器增益之前,驗證是否存在以下條件:1.HSS模塊、液壓執行器和LVDT變壓器完整。
2.控制器增益設置為1(雙列直插式開關S3極8為關閉)。有關控制器增益開關設置,請參閱表3-3。3、指定塊地址中的校準命令位在S3中設置為0(正常操作)。4.S4中指定的塊地址中的GO/HOLD位為設置為0(保持)。
5、汽輪機離線。要調整控制器增益:
HONEYWELL TC-CCR014卡件模塊1.輸入25%的職位需求(通過操作員界面),50%、75%和90%,打開閥門。觀察
每個需求水平的節流閥。閥門應響應時,在任何需求水平上都不會出現波動。
2.輸入25%的職位需求(通過操作員界面),50%、75%和90%,關閉閥門。觀察
每個需求水平的節流閥。閥門應在每個需求水平上做出響應而不發生振蕩。
3、止回閥操作。如果閥門運行平穩需求水平,繼續。如果閥門振蕩,請轉至步驟7。
4、卸下HSS模塊并提高控制器增益(開關2)切換到下一個設置。例如,如果增益為1(極8閉合),將增益更改為2(閉合極7,開路極8)。
Before tuning the controller gain, verify that the following con
ditions exist:
1. Calibration of the HSS module, hydraulic actuator and
LVDT transformer is complete.
2. The controller gain is set to 1 (dipswitch S3 pole 8 is
closed). Refer to Table 3-3 for controller gain switch settings.
3. The calibration command bit in the block address specified
in S3 is set to 0 (normal operation).
4. The GO/HOLD bit in the block address specified in S4 is
set to 0 (HOLD).
5. The turbine is off-line.
To tune the controller gain:
1. Enter position demands (via the operator interface) of 25%,
50%, 75% and 90%, opening the valve. Observe the response of
the throttle valve at each demand level. The valve should
respond without oscillating at any level of demand.
2. Enter position demands (via the operator interface) of 25%,
50%, 75% and 90%, closing the valve. Observe the response of
the throttle valve at each demand level. The valve should
respond without oscillating at each level of demand.
3. Check valve operation. If the valve operates smoothly at all
demand levels, continue. If the valve oscillates go to Step 7.
4. Remove the HSS module and raise the controller gain
(switch 2) to the next setting. For example, if the gain is 1 (pole
8 is closed), change the gain to 2 (close pole 7, open pole 8).
