Analysis of the Zero-Pressure-Difference Point and Determination of the Pump Head in Distributed Power System

Abstract:

Using pressure diagram to analyze the pressure distribution of distributed power system when the zero-pressure-difference point is in different positions. Conclusions can be drawn as follows: the zero-pressure-difference point should be between the critical point and heat source to eliminate the energy consumption of regulators. And as a result the transmission energy consumption of the system becomes lowest. When the zero-pressure-difference point is in different positions between the critical point and heat source, arrangements of pumps of the system are different. But the total output power of the pumps is the same. The zero-pressure-difference point and the schemes for pump head can be conveniently determined by graphical method like pressure diagram or numerical method.
