Is remote startup required for the catalytic main fan?

As the title suggests, let’s discuss whether the primary fan units in use and those on standby should have an option for remote start via the DCS. By the way, can all large-scale units, including those driven by motors, steam turbines, and gas turbines, be started remotely?
Both our primary and backup units need to be started on-site in the power distribution room. The control room simply sends a signal to the power distribution room once the logical conditions are met, and then the start button is pressed.
There’s absolutely no need for that. Starting large-scale power units isn’t something that can be done just by wishing it to happen; an electrician needs to check and confirm it first. Otherwise, what if starting such units causes the entire plant’s power grid to go down?
Large-scale equipment and critical operations must be started only after being checked and confirmed by a designated person.
Remote startup of large-scale units is not permitted; normal startup of such units can only take place after all relevant personnel from the equipment, safety, production, maintenance, and workshop departments are present to conduct on-site verification! ! !
The startup of many devices has come at a costly price! The start-up and shutdown of large-scale equipment require confirmation from personnel in various fields before they can be carried out!
Here, the startup process is initiated by the Equipment Department, which organizes the workshops, electricians, fitters, instrument technicians and other relevant teams to go to the site to verify that everything is in order before starting the operation
There is a checklist for pre-startup inspections; the system is only started after on-site inspections are conducted as required, so remote startup is unreasonable.
In a DCS, there is usually a start-up interlock: only when the start-up conditions are met does the DCS send a signal allowing start-up, after which the operator can press the start button to initiate the process. The startup of large-scale units is generally controlled by the DCS in terms of startup conditions, but it must be carried out on-site. To prevent problems during startup when no one is on site, in addition, the startup of the large units in our installation requires that personnel from the control room and electrical control departments come to the site. Prevent grid fluctuations and mechanical gauge issues during startup.
