The generated energy of a generating set, gives data to control group at this time, and control group passes through electric control starting relay control therein one
A generating set stops working, to guarantee the efficiency power generation of generator；If less than demand electricity consumption about one power generation of generated energy
The generated energy of unit, at this point, giving data to control group, control group controls one of generator by electric control starting relay
Group is started to work, at this point, generated energy not only meets use demand, but also guarantees that generator will not work overloadingly.
Embodiment two:
A kind of Ship Power Station is based on generator load rate-diesel engine thermal efficiency coordinated control system, packet referring to FIG. 1-2,
It includes several generating sets, several diesel engine units, control group, the center of supply and several start and stop mechanisms, diesel engine unit and passes through diesel engine
Transmission flywheel connection generating set in generator armature spindle, start and stop mechanism is installed in diesel engine unit, start and stop mechanism and bavin

Property connection, be electrically connected between control group and the center of supply, the quantity of generating set is maximum according to practical Ship Power Station generated energy
The case where load, is determined.
The present embodiment manages in such a way that the peak load rate of every generating set is certain value, in this way to manage
In, when increasing machine, peak load rate k1 generally takes 0.8~0.85, and taking power grid minimum power allowance is 0.2~0.15.Network of ship
Power factor the higher person takes the larger value, if power factor of electric network is especially low, rate of load condensate k1 can only take 0.75 even lower value,
Certain power factor is especially high, and rate of load condensate k can get 0.9.
Rate of load condensate k2 should be smaller than increasing machine rate of load condensate k1 when subtracting machine, substantially small by 0.05~0.1, takes the power grid maximum power allowance to be
1.6~1.7.Explicit value need to be determined that principle is by ship actual load, a certain larger because increasing if original single-unit operation
Cause increasing machine parallel running after load, after the load is out of service, should ensure that, which can generate the automatic machine that subtracts, is instructed.
Increasing machine rate of load condensate
Subtract machine rate of load condensate
N- generating set number of units, P in formulaLThe actual load of generating set, PRThe rated load of generating set.
Fig. 2 show the generating set operating status figure being managed in such a way that peak load rate is certain value, the figure
What is indicated is that increasing machine rate of load condensate takes 0.8, subtracts the operating status figure that machine rate of load condensate takes 0.7.
This management mode to need parallel running unit number of units be less than or equal to 3 in the case where be it is relatively inexpensive,
From Figure 2 it can be seen that parallel running unit number of units increases, grid power deposit allowance increases therewith.

It connects, control group includes PLC controller, is electrically connected between generating set and the center of supply, electric between diesel engine unit and control group
Property connection, be electrically connected between control group and the center of supply, the quantity of generating set is maximum according to practical Ship Power Station generated energy
The case where load, is determined.
The present embodiment manages in such a way that power station power headroom is certain value, and power station power headroom refers to electric online operation machine
The difference of total load power is power headroom in all performance numbers and current electric grid that group should be able to issue.The increasing machine power headroom of setting
Numerical value is by depending on power station installation quantity and the number of units of the most Parallel sets of need.Generally when only needing two unit parallel connections, it can set
It is scheduled on 0.2 or so；When needing three, four unit parallel connections, 0.3 or so can be scheduled on.Subtract machine power headroom to omit than increasing machine power headroom
It is big, it generally takes bigger than increasing machine by 0.1~0.2 or so.
It can be seen that needing long-time parallel running unit number of units much more economical in this management mode, otherwise just less passing through
Ji.
The premise of rated loan condition is needed in the thermal efficiency, ship power station management system is based on generator institute's generated energy and reality
