Problems solved by technology
This method is barely feasible for a system with a very simple control strategy, and it is likely to cause a decrease in the utilization rate and a waste of energy in the actual operation of the cogeneration system.
At the same time, sometimes joint debugging of multiple devices is required, and the experimental site cannot meet the requirements at all, which seriously hinders the development progress of the new control strategy
[0005] Another way is to pass a large number of calculations and software simulation tests. The simulated control system is far from the actual control system, and the control effect is also quite different from the actual control system.

The invention discloses a testing platform and method for a combined cooling, heating and power system. The testing platform comprises a combined cooling, heating and power simulation system, a programmable signal acquisition and conversion system and a control system. The programmable signal acquisition and conversion system is used for building communication between the combined cooling, heating and power simulation system and the control system, conducting analog-digital conversion and signal processing on control signals of the control system, transmitting the processed control signals to the combined cooling, heating and power simulation system, and meanwhile feeding feedback signals of the combined cooling, heating and power simulation system back to the control system through a communication interface. Due to the fact that the testing platform for a combined cooling, heating and power control system is established, the progress of development of the combined cooling, heating and power control system can be accelerated, and the development cycle is shortened greatly.
Description
technical field [0001] The invention relates to the simulation field of a combined cooling, heating and power system, in particular to a test system and a testing method for a combined cooling, heating and power system based on TRNSYS. Background technique [0002] Environmental and energy issues are major issues facing the world today and need to be resolved urgently. With the vigorous promotion of the sustainable development strategy and the continuous enhancement of people's awareness of energy conservation and environmental protection, the combined cooling, heating and power system has gradually become one of the effective measures to improve environmental quality and energy utilization. Cogeneration is an energy supply system that integrates cooling, heating (heating and hot water supply) and power generation based on the concept of energy cascade utilization. Combined cooling, heating and power supply uses cascaded energy of different qualities. The higher-grade energ...
