Step S200: if determining that all buses stop obtaining the power grid electric energy of the power grid according to the state, control
Bus to be powered in all buses obtains the electric energy of generator, so that the bus to be powered in all buses is negative
Carry power supply.
If determining that all buses 101 stop obtaining power grid electric energy according to state, to guarantee that bus 101 can continue to be negative
102 normal power supplies are carried, control equipment 12 can control generator 103 and export electric energy to the bus 101 of power-off.
Specifically, switch disjunction instruction can be generated in control equipment 12, the switch disjunction is instructed by communication equipment 11
The incoming breaker being sent on every road bus 101, and it is sent to the normally opened open circuit for being separately connected adjacent two-way bus 101
Device.Incoming breaker and normally opened breaker can be in an off state according to the movement of switch disjunction instruction execution separating brake.
Also it to avoid malfunction that accidentally control, such as incoming breaker is caused although to obtain switch disjunction instruction, but does not hold
The movement of row separating brake and keep closed state.By preset duration after sending switch disjunction instruction, controlling equipment 12 can
With according to the state of the most freshly harvested incoming breaker of communication equipment 11 and normally opened breaker again determine incoming breaker and often
Whether circuit breaker is in off-state.
If it is determined that there are also incoming breakers or normally opened breaker to be not in off-state, control equipment 12 can be to host computer
The information of control mistake is sent, and terminates this control flow.
If it is determined that all incoming breakers and normally opened breaker are in off-state, after control equipment 12 then continues to execute
Afterflow journey, such as control equipment 12 continue to generate switch disjunction instruction, and are sent to the leading-out terminal for being separately connected every road bus 101
With each wire-outgoing breaker of load 102.Each wire-outgoing breaker can according to switch disjunction instruction execution separating brake movement and
It is in an off state.
Also to avoid malfunction from leading to accidentally control, by preset duration after sending switch disjunction instruction, equipment 12 is controlled
Whether each wire-outgoing breaker can also be determined again according to the state of the most freshly harvested each wire-outgoing breaker of communication equipment 11
It is in off-state.
If it is determined that there are also wire-outgoing breakers to be not in off-state, it is wrong that control equipment 12 can also send control to host computer
Information accidentally, and terminate this control flow.
If it is determined that all wire-outgoing breakers are in off-state, control equipment 12 then continues to execute follow-up process, such as
It controls equipment 12 and generates generator enabled instruction, and generator enabled instruction is sent to by generator by communication equipment 11.
After sending generator enabled instruction, accurately to determine which generator starting is run successfully, communication equipment 11 can
With the output voltage of the lasting each generator of acquisition, control equipment 12 then can be by judging whether each output voltage reaches
Predeterminated voltage and determine whether the generator starts and run successfully.
May be long the time required to the starting of some generators, for it is accurate determine which generator starting operation at
Function by a delay duration is, for example, 30 seconds after sending generator enabled instruction, and control equipment 12 can also be according to communication
The output voltage of the most freshly harvested each generator of equipment 11 determines which generator starting is run successfully.
In the present embodiment, according to the output power of preset every generator, controlling equipment 12 can incite somebody to action control equipment 12
The output power of the generator of all operations adds up, and obtains the gross output of generator.
In general, if all generators all start operation, then gross output can satisfy the need of all buses 101
It asks.If but the starting operation of part generator, then gross output then meets the needs of part bus 101.It therefore, can be by pre-
If the priority of load 102 come so that important load 102 preferentially restores electricity.
Specifically, pre-setting the power supply priority of each load 102 in control equipment 12, wherein every road load 102
Power supply priority height can depend on it is each load 102 significance level.For example, load 102A is in data center
Data server, and loading 102B is the lighting apparatus in data center, then the power supply priority of load 102A can be higher than
Load the power supply priority of 102B.In addition, also pre-setting the demand power of each load 102 in control equipment 12, wherein
The demand power of each load 102 can be the load 102 and operate normally the power needed.
Further, control equipment 12 can by the power supply priority sequence from high to low of preset each load 102,
The sum of successively the demand power of each load 102 is added and obtains demand power.At the same time, control equipment 12 can also be sentenced
Whether the sum of disconnected acquisition demand power of addition every time changes to matches with gross output.Wherein, matching indicate demand power it
With change to the difference of gross output in such as 10% default error range.For example, load 102A, load 102B and
The power supply priority for loading 102C is successively load 102A → load 102B → load 102C from high to low, and control equipment 12 first will
The demand power of 102A is loaded as the sum of demand power, and the sum of judges the demand power and whether is matched with gross output.
If mismatching and being less than gross output, control equipment 12 will load the demand power of the demand power and load 102B of 102A again
It is added, and judges after being added whether the sum of the demand power changes to and matched with gross output.If also mismatching and being also less than
Gross output, control equipment 12 then again by the demand power for loading 102A, load the demand power and load 102C of 102B
Demand power is added, and determine be added again after the sum of the demand power change to and matched with gross output.Wherein, this implementation
Example described in matching can refer to be compared the two difference within a preset range, preset range can be such as -5% to+
5%.
By successively judging whether to match, when the sum of demand power is changed to and matched with gross output, equipment is controlled
12 can determine the corresponding bus 101 of the sum of matched demand power, wherein the corresponding bus 101 is and demand power
The sum of the corresponding bus 101 preferentially connected for electric loading 102, the corresponding bus 101 it is also excellent to need in all buses 101
The bus to be powered 101 first powered.For example, bus 101 has 5 tunnels, control equipment 12 determines the preceding 3 road bus of highest priority
The sum of 101 demand power is matched with gross output, and the preceding 3 road bus 101 of highest priority is then 3 tunnels bus to be powered
101。
In the present embodiment, the output end of each generator can connect generator doubling bus 101, and every road bus
101 can be connect by simultaneously machine bus breaker with generator doubling bus 101.Certainly, it is normally obtained in every road bus 101
