產品詳情資料

1.系統和控制器的配置要重點考慮可靠性和負荷率(包括冗余度)指標。通訊負荷率控制在合理范圍內，控制器的負荷率盡可能均衡，避免“高負荷”問題的發生。

2.系統控制邏輯的分配，不宜過分集中在某個控制器上，主要控制器應采用冗余配置。

3.電源設計合理可靠。注意電源設計的負荷率和電源的冗余配置方式，保證兩路獨立電源。

4.注重DCS系統接口的可靠性，注意重要接口的接口方式和冗余度。

5.DCS系統接地按廠家要求執行，避免接地問題造成系統大面積故障。應注重考慮系統的抗干擾措施，I/O通道應強調隔離措施。重視電纜質量與屏蔽，重要信號及控制使用計算機通訊屏蔽電纜。

6.根據設備運行特點和工況下機組處理緊急故障的要求，配置操作員站和后備手操裝置。緊急停機停爐按鈕配置，應采用與DCS分開的單獨操作回路。

7.對于保護系統，采用多重化信號攝取法。合理使用閉鎖條件，使信號回路具有邏輯判斷能力。

8.調試期間按照調試大綱、辦法，對所有邏輯、回路、工況進行測試，確保各參數設置正確合理。

英文產品詳細信息

1. The configuration of the system and controller should focus on reliability and load rate (including redundancy) indicators. The communication load rate should be controlled within a reasonable range, and the load rate of the controller should be as balanced as possible to avoid the occurrence of "high load" problems.

2. The allocation of system control logic should not be overly concentrated on a certain controller, and the main controller should adopt redundant configuration.

3. The power supply design is reasonable and reliable. Pay attention to the load rate of power supply design and the redundant configuration of power supply to ensure two independent power sources.

4. Pay attention to the reliability of DCS system interfaces, and pay attention to the interface methods and redundancy of important interfaces.

5. The grounding of the DCS system shall be carried out according to the manufacturer's requirements to avoid grounding issues causing large-scale system failures. Attention should be paid to considering anti-interference measures of the system, and I/O channels should emphasize isolation measures. Pay attention to cable quality and shielding, and use computer communication shielded cables for important signals and controls.

6. According to the operating characteristics of the equipment and the requirements for handling emergency faults of the unit under working conditions, an operator station and backup manual operation device shall be configured. The emergency shutdown button configuration should adopt a separate operating circuit from DCS.

7. For the protection system, the multiple signal acquisition method is adopted. Reasonably use the blocking conditions to enable the signal circuit to have logical judgment ability.

During the debugging period, all logic, circuits, and working conditions shall be tested according to the debugging outline and methods to ensure that all parameter settings are correct and reasonable.
