Performance Optimization and Test on Primary Frequency Regulation of Digital Electric-Hydraulic Control System of 50 MW Biomass Power Generation Units

The paper introduces implementation of primary frequency regulation of digital electric-hydraulic(DEH) control system of unit No.1 in Zhanjiang 2×50 MW CFB generation project.It analyzes problems in primary frequency regulation in DEH and gives a proposal for performance optimization.The test and operation show that primary frequency performance characteristic is improved by performance optimization and hence the requirement of power grid is met.
