在线下装程序一定要Westinghouse西屋非常谨慎。CCPP涉及Westinghouse西屋煤气、蒸汽和发电机组，都是对安全要求极高的设备。稍有不慎，轻则会出现机组退出，严重者会出现爆炸事故。来不得半点马虎。为此，针对CCPP这样的工艺特点，在下载前，必须做好充分的事故应急预案工作，制订切实有效的安全防范措施，如将该控制器控制的所有重要运行设备，如运行允许全部切换为就地运行，所有通讯点进行隔离，并将与其对应控制器有联锁关系点和不同控制器机柜的硬接线点强制，防止新旧程序在下装瞬间，回到执行状态时的初始扫描过程中，软件初始值引起失控状态值输出，导致设备误动作。为此，Westinghouse西屋程序下装工作尽量选择在机组停运期间，采用相对安全的增量下装方式，少用全下装。总之，现场调试时的程序下装思维不能照搬照抄到生产运行中，因为现场调试属于模拟运行，而生产过程中是带负荷运行。

Westinghouse must be very cautious when downloading programs online. CCPP involves Westinghouse gas, steam, and generator sets, all of which have extremely high safety requirements. Slight carelessness can cause the unit to exit, or in severe cases, an explosion accident. I can't come at all carelessly. Therefore, in response to the process characteristics of CCPP, sufficient emergency plans for accidents must be prepared and effective safety precautions must be formulated before downloading. For example, all important operating equipment controlled by the controller, if allowed to operate, must be switched to local operation, all communication points must be isolated, and interlocking points with their corresponding controllers and hard wiring points of different controller cabinets must be enforced, Prevent the initial value of software from causing uncontrolled output during the initial scanning process when new and old programs are uninstalled and returned to the execution state, leading to device malfunction. For this reason, Westinghouse's program installation work should try to choose a relatively safe incremental installation method during the shutdown period of the unit, and minimize the use of full installation. In short, the thinking of program installation during on-site debugging cannot be copied into production operation, because on-site debugging belongs to simulated operation, while the production process is under load operation.
