摘要
Abstract
Discrepancy between flow characteristic of steam turbine valve and practical flow characteristic might affect load control precision and primary frequency modulation of the unit. Taking 330 MW two-stage industrial extraction steam heat-ing unit as an example,experiments on valve flow under single valve mode and sequence valve control mode were carried out. Meanwhile,analysis and optimization on experimental data was conducted. Flow characteristic curve of the valve after optimization got better continuity and linearity and improved load control precision and qualified rate of primary frequency modulation of the unit.关键词
