City's electrical instrumentation can be realized data monitorings such as line voltages;
Comprehensive management apparatus manages respectively each collected equipment, and generating to whole system and detecting with electric process, by comprehensive power management algorithm, according to the data that collect, reasonably control diesel generating set start and stop, multi-machine parallel connection, multi-machine parallel connection grid-connected and generating set and civil power seamless switching, thereby realize centralized control, realize uninterrupted power supply, energy-conservation power supply;
By comprehensive management apparatus, monitor city's electricity condition, and control on this basis the start and stop of generating set.After civil power dead electricity, powered to the load by separate unit or many generating set parallel connections; Behind city power recovery, first by grid-connected to generating set and the civil power of operation, then transferring load, by mains-supplied, avoid secondary to have a power failure, realize generating set and civil power seamless switching;
By comprehensive management apparatus, monitoring system load condition, and the corresponding generating set of start and stop on this basis, according to the power of the load generated output of every generating set of allotment in real time, solved heavy load and started the large problem of immediate current simultaneously;
Touch-screen shows the data message about generating set, civil power, load of comprehensive management apparatus transmission in real time, simultaneously, operator sends order by touch-screen to comprehensive management apparatus, control start-stop of generator set machine, and the closing point of air switch, realize multi-machine parallel connection, multi-machine parallel connection grid-connected and generating set and civil power seamless switching;
The present invention can realize the monitoring of the number of number of units to any generating set, civil power way, load, has extensibility.For a fairly large number of occasion of monitoring, can utilize the mode that increases communication interface, accelerate communication speed.
Technique effect of the present invention is: 1, centralized monitor, reduce management cost, and accelerate failure response speed, increase work efficiency; 2, touch screen operation is convenient, directly perceived, is easy to observe; 3, the start and stop of Long-distance Control generating set, parallel connection, grid-connected, realize centralized control; 4,, according to load, the corresponding unit of start and stop, solves heavy load and starts the large problem of transient starting electric current; 5, Long-distance Control generating set and civil power auto-parallel, seamless switching; 6, system has extensibility.
