Calculating Of Heat Consumption Index And Analysis Of Energy Saving On Substation

For the large-scale central heating system, substation's operation effect take an important role for the whole heating net, and substation's energy consumption is an important part in energy saving. With the heat metering popularize in China, it is very much worth studying that substation's control and energy saving situation in variable water volume. In this thesis, take the substation as a whole research object. By calculating and comparing typical substation's design load and consumption load, get the heat consumption index. On the base of this, set up a heat consumption index determine and forecast model, further verify the model's validity with calculation. In the course of design load calculating, put forward a new simplify method handle the meteorological data that are not hourly, also verify the method's precision with the data of typical meteorological year. Furthermore, aim at the variable water volume's character introduce the principle and control method of pump work in variable voltage variable frequency, and utilize technical economy way analysis the energy saving effect, have given the partially city's relative electrical saving rate and static pay back period of pump with VVVF control. Analysis substation's energy situation by site testing, theory calculating and verify calculating, discuss the energy saving potential on substation.
