Abstract:

Building cooling, heating and power (BCHP)system is a highly efficient energy use patterns, which can provide electricity, cooling and heating.A distributed control system is used due to complication of the BCHP system involving different equipments, different seasons and different users.In this paper, a distributed control system based on programmable logical controller (PLC)and supervising computer is developed.It makes the whole system run automatically in different season work.Its control hardware and software are introduced and its control strategy is analyzed.
