[0025] In order to solve the technical problems in the prior art that the heat source temperature range of the ORC power generation device adapted by the test system is narrow, the types of working fluids are few, and the device scale is small, an embodiment of the present application provides a test system. The test system includes an organic Rankine cycle power generation device and a test device.

The following is a detailed explanation.

[0026] See also Figure 1 , Figure 1 It is a schematic diagram of an embodiment of the test system of the present application.

[0027] In one embodiment, the test system includes an organic Rankine cycle power generation device 10 and a test device 20. The test device 20 includes a heat source device 21, which is connected to the organic Rankine cycle power generation device 10, and the heat source device 21 is used to cyclically output a heat carrier to the organic Rankine cycle power generation device 10. The test device 20 also includes a cold source device 22, which is connected to the organic Rankine cycle power generation device 10, and the cold source device 22 is used to cyclically output a cooling medium to the organic Rankine cycle power generation device 10. The test device 20 also includes a load device 23, which is connected to the organic Rankine cycle power generation device 10, and the organic Rankine cycle power generation device 10 is used to output electrical energy to the load device 23.

[0028] In this embodiment, the heat source device 21 provides a heat carrier (which may be heat transfer oil, etc.) to the organic Rankine cycle power generation device 10, and the cold source device 22 circulates and outputs a cooling medium to the organic Rankine cycle power generation device 10, so as to establish a working medium power cycle of the organic Rankine cycle power generation device 10, so as to perform a performance test on the organic Rankine cycle power generation device 10. In addition, since the electric energy output by the organic Rankine cycle power generation device 10 during the test cannot be incorporated into the power grid, the load device 23 in this embodiment is used to absorb the electric energy output by the organic Rankine cycle power generation device 10.

[0029] In the above manner, the heat source device 21 of this embodiment can provide a heat carrier with a higher temperature, thereby widening the heat source temperature range of the organic Rankine cycle power generation device 10 adapted by the test system. In addition, the test system of this embodiment has power cycle performance test conditions for different types of working fluids (alkanes, freons, etc.) of the organic Rankine cycle power generation device 10, thereby widening the types of working fluids of the organic Rankine cycle power generation device 10 adapted by the test system. This embodiment is also conducive to the test system being adapted to a larger scale of organic Rankine cycle power generation devices 10.

[0030] The organic Rankine cycle power generation device 10 according to an embodiment of the present application is described below.

[0031] In one embodiment, the organic Rankine cycle power generation device 10 includes a generator set 11, a working fluid pump 12, a preheater 13, an evaporator 14, a condenser 15 and a regenerator 16. The input end and the output end of the working fluid pump 12 are respectively connected to the generator set 11. The preheater 13 is connected between the output end of the working fluid pump 12 and the generator set 11. The evaporator 14 is connected between the preheater 13 and the generator set 11. The condenser 15 is connected between the input end of the working fluid pump 12 and the generator set 11. The regenerator 16 is connected between the output end of the working fluid pump 12 and the preheater 13, and the regenerator 16 is also connected between the condenser 15 and the generator set 11.

[0032] The generator set 11 may include a turbine expander. The input end of the working fluid pump 12 is connected to the output end of the condenser 15, the output end of the working fluid pump 12 is connected to the liquid phase working fluid input end of the regenerator 16, the liquid phase working fluid output end of the regenerator 16 is connected to the input end of the preheater 13, the output end of the preheater 13 is connected to the input end of the evaporator 14, the output end of the evaporator 14 is connected to the input end of the turbine expansion generator set 11, the output end of the turbine expansion generator set 11 is connected to the gas phase working fluid input end of the regenerator 16, and the gas phase working fluid output end of the regenerator 16 is connected to the input end of the condenser 15. After the working fluid is pressurized by the working fluid pump 12, it passes through the regenerator 16, the preheater 13 and the evaporator 14 in sequence. The working fluid is heated to a gas phase working fluid after heat exchange with the heat carrier output by the heat source device 21 in the preheater 13 and the evaporator 14. The gas phase working fluid enters the turbine expander of the generator set 11 to expand and do work, and the turbine expander drives the generator to rotate to generate electricity and output electrical energy. The expanded exhaust steam exchanges heat with the liquid working fluid output by the working fluid pump 12 in the regenerator 16 and is cooled, then enters the condenser 15 to be condensed into liquid working fluid, and then enters the working fluid pump 12 for pressure increase, and this cycle is repeated to complete the working fluid power cycle.

[0033] It should be noted that the heat source temperature adapted by the organic Rankine cycle power generation device 10 of this embodiment is medium-high temperature (the highest temperature can reach 310°C, etc.), and the organic Rankine cycle power generation device 10 of this embodiment is required to have a high thermoelectric conversion efficiency, so a regenerator 16 is provided. The liquid working fluid output by the working fluid pump 12 exchanges heat with the exhaust steam output by the generator set 11 in the regenerator 16, and further utilizes the waste heat of the exhaust steam output by the generator set 11, which can improve the energy utilization rate of the system, and the temperature of the exhaust steam is reduced in advance after heat exchange, and then enters the condenser 15 for condensation, which can reduce the requirements for the condensation load of the condenser 15, thereby helping to reduce the test cost.

[0034] Of course, in other embodiments of the present application, the heat source temperature adapted to the organic Rankine cycle power generation device 10 may also be low temperature (eg, as low as 90° C.), and the organic Rankine cycle power generation device 10 may omit the regenerator 16 , which is not limited here.

[0035] The heat source device 21 of the embodiment of the present application is described below.

[0036] Please also read Figure 2 , Figure 2 It is a schematic diagram of an embodiment of the heat source device of the present application.

[0037] In one embodiment, the output end of the heat source device 21 is connected to the evaporator 14 and the preheater 13 in sequence, and the heat source device 21 is used to output heat carrier to the evaporator 14 and the preheater 13, so that the heat carrier heats the working fluid output by the working fluid pump 12 through the evaporator 14 and the preheater 13. The heat carrier just output from the heat source device 21 has a higher temperature, so the heat carrier first reaches the evaporator 14 to heat the working fluid in the organic Rankine cycle power generation device 10 into a gas phase working fluid, which has a higher heating efficiency. At the same time, after the heat carrier heats the working fluid, its own temperature drops to a certain extent. At this time, the heat carrier reaches the preheater 13 to preheat the working fluid. Since the preheating link of the preheater 13 requires a lower temperature for the heat carrier than the evaporator 14, the heat carrier of this embodiment sequentially passes through the evaporator 14 and the preheater 13, which can reasonably utilize the heat energy of the heat carrier, which is conducive to improving the energy utilization rate and utilization efficiency of the entire system. In addition, the working fluid of this embodiment is heated by the two heating processes of the preheater 13 and the evaporator 14, which is conducive to improving the overall heating efficiency of the working fluid.

[0038] In one embodiment, the heat source device 21 may be a heat carrier boiler skid or the like. Specifically, the heat source device 21 includes a boiler 211 and a burner 212. The boiler 211 is connected to the organic Rankine cycle power generation device 10, and the boiler 211 is used to circulate and output the heat carrier to the organic Rankine cycle power generation device 10. The burner 212 is disposed in the boiler 211, and the burner 212 is used to ensure that the fuel and air are mixed and burned in an appropriate manner, and provide heat to heat the heat carrier in the boiler 211.

[0039] In this embodiment, the heat provided by the burner 212 heats the heat carrier in the boiler 211, and the power of the burner 212 is adjusted to adjust the temperature of the heat carrier output by the boiler 211. The temperature of the heat carrier in this embodiment is 90°C to 310°C, which means that the test system of this embodiment can cover low-temperature, medium-temperature and high-temperature organic Rankine cycle power generation devices 10. The heat source device 21 of this embodiment can provide a higher temperature heat carrier, thereby widening the heat source temperature range of the organic Rankine cycle power generation device 10 adapted to the test system. A temperature transmitter is provided on the pipeline to read the temperature of the heat carrier inlet and outlet. The flow rate of the heat carrier can be controlled by the valve on the pipeline and measured by the flowmeter.

[0040] The heat source device 21 also includes a chimney 213, an oil-gas separator 214, an expansion tank 215, an oil storage tank 216, a first oil pump 217, and a second oil pump 218. The input end of the first oil pump 217 is connected to the liquid phase output end of the oil-gas separator 214, the output end of the first oil pump 217 is connected to the input end of the boiler 211, the output end of the boiler 211 is connected to the organic Rankine cycle power generation device 10 (specifically, the output end of the boiler 211 is connected to the evaporator 14 of the organic Rankine cycle power generation device 10), the output end of the organic Rankine cycle power generation device 10 is connected to the input end of the oil-gas separator 214, and the gas phase output end of the oil-gas separator 214 is connected to the expansion tank 215. The burner 212 is used to generate high-temperature flue gas to heat the heat carrier in the boiler 211, and the second oil pump 218 and the oil storage tank 216 are used to inject and store oil into the boiler 211. The heat carrier is provided by the outside or the oil storage tank 216, and is injected into the system through the second oil pump 218. After obtaining heat energy from the boiler 211, the heat carrier supplies heat to the organic Rankine cycle power generation device 10. The cooled heat carrier passes through the oil-gas separator 214 and is pressurized by the first oil pump 217, and returns to the boiler 211 to be reheated. The excess heat carrier in the expansion tank 215 flows into the oil storage tank 216 through the overflow pipeline, and the gas in the expansion tank 215 and the oil storage tank 216 is discharged through the pipeline. The chimney 213 is used to discharge flue gas.

[0041] The cold source device 22 of the embodiment of the present application is described below.

[0042] In one embodiment, the output end of the cold source device 22 is connected to the input end of the cold source device 22 through the condenser 15, and the cooling medium output by the cold source device 22 cools the working fluid output by the generator set 11 through the condenser 15. The working fluid pump 12 is used to increase the pressure of the working fluid flowing through the condenser 15 and transmit it to the generator set 11.

[0043] Specifically, the cold source device 22 includes a cooling tower 221 and a circulating pump 222. The output end of the cooling tower 221 is connected to the input end of the cooling tower 221 through the condenser 15. The circulating pump 222 is connected between the cooling tower 221 and the condenser 15, and the circulating pump 222 is used to circulate and pump the cooling medium to the condenser 15. The input end of the circulating pump 222 is connected to the output end of the cooling tower 221, the output end of the circulating pump 222 is connected to the cooling medium input end of the condenser 15 and the generator set 11, and the cooling medium output end of the condenser 15 and the generator set 11 is connected to the input end of the cooling tower 221. The cooling medium output by the cooling tower 221 is pressurized by the circulating pump 222 and sent to the condenser 15 to exchange heat with the working medium, enters the oil cooler of the generator set 11 to exchange heat with the lubricating oil, and the cooling medium absorbs heat and returns to the cooling tower 221 for cooling, thereby completing the cooling medium cycle. The cooling tower 221 uses automatic and manual replenishment methods to make up for the evaporation loss and splash loss of the cooling medium. The flow rate of the cooling medium can be controlled by the pipeline valve and read by the flow meter. A temperature transmitter is set on the pipeline to read the inlet and outlet temperatures of the cooling medium.

[0044] Optionally, the cooling medium may be cooling water or the like, and the temperature of the cooling medium may be 15° C. to 40° C. In addition, the cooling tower 221 has a supplementary end 223 , and the supplementary end 223 is used to supplement the cooling medium to the cooling tower 221 .

[0045] The load device 23 of the embodiment of the present application is described below.

[0046] Please also read Figure 3 , Figure 3 It is a schematic diagram of an embodiment of a load device of the present application.

[0047] In one embodiment, the load device 23 includes a ring main unit 231 and a load box 232. The ring main unit 231 is connected to the organic Rankine cycle power generation device 10. The load box 232 is connected to the ring main unit 231, and the electric energy output by the organic Rankine cycle power generation device 10 is transmitted to the load box 232 through the ring main unit 231 for consumption.

[0048] Furthermore, for the case where the output voltage level of the organic Rankine cycle power generation device 10 is different from the voltage level of the load box 232, the load device 23 also includes a transformer 233, and the ring main unit 231 is connected to the load box 232 through the transformer 233. The transformer 233 adjusts the voltage level of the output voltage of the organic Rankine cycle power generation device 10 to be consistent with the voltage level of the load box 232.

[0049] For example, the load box 232 can be in the form of a dry resistor or the like. Since the electric energy output by the organic Rankine cycle power generation device 10 cannot be connected to the power grid during the test, the electric energy output by the organic Rankine cycle power generation device 10 is consumed by the load box 232 in this embodiment. The generator set 11 of the organic Rankine cycle power generation device 10 outputs power to the input end of the ring main unit 231, and the output end of the ring main unit 231 is connected to the input end of the transformer 233. The voltage level of the voltage output by the generator set 11 can be 10 kV, and the transformer 233 reduces the voltage level of 10 kV to the voltage level of 0.4 kV. The output end of the transformer 233 is connected to the load box 232, and the power output of the test is consumed by the load box 232.

[0050] Of course, in other embodiments of the present application, when the output voltage level of the organic Rankine cycle power generation device 10 is consistent with the voltage level of the load box 232 , the load device 23 may eliminate the transformer 233 , which is not limited here.

[0051] It should be noted that the test system of the embodiment of the present application is equipped with a test control system, which includes a test instrument, a SIS control cabinet and a host computer, a PLC control cabinet and a host computer. During the test, parameters such as temperature, pressure, liquid level, vibration, displacement, and rotation speed need to be measured. In order to ensure the safety of the test system, all electrical equipment and instruments are explosion-proof. When the working fluid to be tested is a flammable medium, a combustible gas alarm and a fire detector are set up at the test site. The test data is transmitted to the computer through the PLC control cabinet and the SIS control cabinet for display and analysis, and the pneumatic control valve, shut-off valve, motor, electric heater and other equipment are controlled by the control cabinet. Due to the explosion-proof characteristics of the test system, the measuring instrument is installed in the on-site test area, and the control room is placed in a safe area. The test system adopts an explosion-proof design as a whole, which can complete the power cycle performance test of different working fluids in the organic Rankine cycle power generation device 10, and has the conditions for testing the performance of different types of working fluids (alkanes, freons).
