Mimic Panel

08/25/2010 6:45 AM

Hello Sir's.

I need your help, the network consists of 56 Switchgears, the client wants the change the all the switchgears, plus they want to install the new mimic panel, in the monitoring room for monitoring purpose, remote control of all the switchgears, and they want to have the option of automatic load shedding, dats if the demand for the particular switchgear increase's more then the allowed demand, the breaker should trip automatically.

Can someone please guide me how this can be achieved, or any supplier who supplies such type of mimic panels. Any catalogue or logic for loadshedding will be highly appreciated.

Thanks and kind regards

Turn the overloads down dat'll shed the load

Move the monitoring equipment to the lounge, much more comfortable.

Mimic panels are a dying technology, most people have gone to SCADA systems with flat screen monitors as HMIs or DCS systems with monitors (depending on size). A system of our size and scope is probably a better candidate for a SCADA system, Invensys/Wonderware has packages that specifically address the needs you stated, as does Siemens with their WinPM Power Monitoring system. I would start there.

know or calculate for the maximum permissible load demand of each circuit of the switchgear(s) and with the appropriate calculation of short circuit and overload protection ratings and proper overload settings on the breaker(s),select and use that breaker(s) to protect your load or for your automatic load shedding.

So if a switchgear is overloaded,as you described above,based on your settings,the breaker would trip automatically.
