Definitions
- a combined heat and power (CHP) system includes a mechanical power source having a mechanical shaft output configured to produce mechanical shaft energy.
- a power split device is coupled to the mechanical shaft output and is configured to variably distribute the mechanical shaft energy to a motor/generator and a chiller.
- the motor/generator is coupled to the power split device and configured to generate electrical energy from the mechanical shaft energy.
- the chiller is coupled to the power split device and is configured to generate chilled liquid from the mechanical shaft energy.
- FIG. 3 is a plot illustrating operation of the CHP system of FIG. 2 for supporting an electrical load and a thermal load from the chiller system.
- a power split device may be used in a combined heat and power (CHP) system to improve operation of the CHP system.
- a mechanical power source that generates mechanical shaft energy may commonly be mechanically coupled to a motor-generator, which uses the shaft energy to produce electrical energy. The electrical energy may then be distributed to an electrical load or to an electrical energy storage system.
- the motor-generator typically in a CHP system that includes a chiller, the motor-generator also supplies electrical energy to the chiller, which uses the energy input for cooling.
- a CHP system operates more efficiently by selectively supplying the mechanical shaft energy directly to the chiller from the mechanical power source.
- system 1 12 is operating in a mode in which an electrical load from grid or load 122 receives priority over a cooling load from chiller system 118. (Alternatively, a cooling load may be equal to zero.) Essentially all of the mechanical shaft energy from ORC system 1 12 is distributed through power split device 114 to motor/generator 116, in order to meet the electrical demand of grid or load 122.
- Load Power is reduced from 1.0 to 0.8 units. This reduction in Load Power is a result of a decreased demand from grid or load 122. Because ORC Output remains constant, the excess mechanical shaft energy from ORC system 112 that is no longer required by grid 122 may be supplied to chiller 118. However, chiller 118 is most likely not able to immediately receive all of the excess shaft energy; instead, the input to chiller 118 from prime mover 112 is gradually increased. As shown in FIG. 3, VCC Power Input steadily increases between 6 and 7 seconds until it reaches 0.2 units.
- electrical energy storage 124 may receive excess electrical energy generated by motor/generator 116, while chiller 118 is ramping up. This is shown in FIG. 3 by the increase to Electrical Energy Storage at time equal to 6 seconds. However, the rate at which electrical energy storage 124 is receiving electrical energy from motor/generator 1 16 decreases as power to chiller 118 increases. At time equal to 7 seconds, VCC Power Input has reached a set point of 0.2 units and chiller system 118 is receiving all of the mechanical shaft energy from prime mover 112 that is not required by motor/generator 116. At this same point in time, electrical energy storage system 124 is consequently at zero.
- VCC Power Input is equal to 0.1 units, meaning that chiller system 1 18 is receiving some mechanical shaft energy from ORC system 112.
- Power from Electrical Energy Storage is equal to zero between time equal to zero and 6 seconds, meaning that ORC system 1 12 is able to provide enough shaft energy to chiller system 1 18 to meet a cooling load of chiller 118.
- control architecture 150 includes a cascaded control scheme, and power split device 114 is controlled by supervisory controller 154 through power controller 120. It is recognized that in additional embodiments of control architecture 150, power split device 1 14 may include its own controller that is directly connected to supervisory controller 154.
- the distribution of shaft energy from power split device 1 14 may also be based upon desired operating conditions for each mechanical shaft of device 114, motor/generator 116 and chiller 1 18, including shaft rpm and torque.
- the shaft distribution from power split device 114 may frequently change as a function of fluctuations in the electrical loads and the cooling loads. Moreover, the distribution may change depending on an operating mode of controller 120 (i.e. whether controller 120 is operating in a mode in which priority is given to motor/generator 116 over chiller 118, or vice versa).
- the demands on chiller system 118 are monitored by supervisory controller 154, whereas the electrical load is monitored through power controller 120. This data, in combination, may be used to control the mechanical energy split by power split device 1 14 and the electrical energy split by power controller 120.
