On the basis of theoretical analysis and experimental techniques for coal-fired power units

a synthesized and integrated optimization scheme was proposed

in response to in-depth optimization of grid performance and the grid performance assessment for coal-fired units.By analyzing factors affecting the gridconnection performance systematically

this program applies four technologies to achieve the optimal performance of FM peaking

such as regulating valve characteristic parameter testing and optimization tuning

coordinated optimization based on dynamic feedforward technique

integrated primary frequency optimization and main steam temperature optimization.Application of this scheme in a 600 MW unit shows this program can enhance the grid-connection performance indexes effectively.
