Abstract

The objective of this research is to simultaneously reduce energy requirements along with rapid and broad load ranges using variable-speed pumps (VSPs) in thermal power plants. This paper proposes a novel algorithm to calculate the operating points of VSP. A case study on the operation optimization of condenser cooling water pump shows that VSP is far superior to fixed-speed pump in terms of energy savings. Vacuum adjustment system is established to improve the capability of thermal power plants in executing rapid load changes. The authors also bring forth a proposal to establish an automatic variable-speed control system to ensure safety, economy, and stability of the units and grid operations.
