Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model provides a kind of ventilation air gas electricity generation system, see Fig. 1, comprise gas electricity unit 4 and external electrical network 1, gas electricity unit 4 and external electrical network are all connected to load 3 by bus 2, gas electricity unit 4 is connected to weary wind admission line 5, the inlet end of weary wind admission line 5 is provided with intake valve controller 6 and is used for controlling its air inflow, intake valve controller 6 is for receiving the control command of cooperation control machine, control the air inflow of weary wind admission line, the dynamic adjustments gas electricity power of the assembling unit exports.
One end that external electrical network is connected with bus 2 is provided with grid-connected power meter scale 8, and grid-connected power meter scale 8 is for gathering and the power factor of site; Grid-connected power meter scale 8 is connected to intake valve controller 6 by cooperation control machine 7, the also site power data that cooperation control machine 7 is uploaded for gathering grid-connected power meter scale, analyzes running status, formulates intake valve controller and reasonably run control command.
Grid-connected power meter scale 8 is for detecting and the power data of site, obtain real-time power factor, and send to cooperation control machine 7, the power factor that cooperation control machine 7 collects for receiving grid-connected power meter scale 8, and the air inflow controlling weary wind admission line 5 by controlling intake valve controller 6.
See Fig. 2, after grid-connected power meter scale 8 work of the utility model ventilation air gas electricity generation system, transmit real-time also site power information, when cooperation control machine 7 obtains the power factor PF in this moment to cooperation control machine 7
tafter, carry out operation and control to judge:
1. as power factor PF
tduring higher than deadband upper limit value, intake valve current state is full admission amount simultaneously, then maintain current air inflow.
2. as power factor PF
tduring higher than deadband upper limit value, intake valve current state is not full admission amount simultaneously, then rated output factor rate of change Δ PF;
When power factor change rate is greater than zero, then assign the operational order that intake valve controller 6 increases air inflow, air inlet increment is (minimum rate of change+Δ PF) times of current air inflow;
When power factor change rate is less than zero, then assign the operational order that intake valve controller 6 increases air inflow, air inlet increment is (minimum rate of change-Δ PF/2) times of current air inflow.
3. as power factor PF
tduring lower than deadband upper limit value, and during higher than deadband lower limit value, intake valve controller 6 maintains current air inflow.
4. as power factor PF
tduring lower than deadband lower limit value, intake valve current state is minimum permission air inflow simultaneously, then gas electricity unit is standby.
5. as power factor PF
tduring lower than deadband lower limit value, intake valve current state is not minimum permission air inflow simultaneously, then rated output factor rate of change Δ PF;
When power factor change rate is greater than zero, then assign the operational order that intake valve controller 6 reduces air inflow, air inlet reduction is (minimum rate of change+Δ PF/2) times of current air inflow;
When power factor change rate is less than zero, then assign the operational order that intake valve controller 6 reduces air inflow, air inlet reduction is (minimum rate of change-Δ PF) times of current air inflow.
At present, not yet there is the ventilation air gas electricity generation system based on power factor examination in domestic market, existing system cannot integral power factor information, unified coordinate ventilation air gas generating set, technical advantage and the economic advantages of its entirety cannot be given full play to.The utility model is a kind of ventilation air gas electricity generation system based on power factor examination, ventilation air gas generating set power can be controlled flexibly export, avoid on the one hand causing because the power factor that is incorporated into the power networks is too low occurring fine, utilize weary general mood body on the other hand according to actual conditions as far as possible, improve comprehensive utilization of energy rate, energy-saving and emission-reduction, have wide development and apply prospect.
