The invention relates to a unit load coordination control method based on a steam turbine regulating valve point. The unit load coordination control method comprises the following steps: (1) revising a regulating valve steam distribution function in the DEH (Digital Electro-Hydraulic Control System) of a steam turbine to eliminate a regulating valve overlapping degree; (2) canceling an original load control or steam pressure control loop in the master control of the steam turbine, and setting a master control instruction of the steam turbine as an open loop function of a load instruction, wherein the master control of the steam turbine does not actively respond to load changes and only participates in regulation during an initial stage of load change or one-time frequency modulation movement; (3) adopting condensation water throttling to participate in load regulation, and quickening the load response of the initial stage of load change; (4) quickening a boiler coal water response rate, and optimizing a coal water overshooting way to improve the integral load change capability of a unit. Compared with the prior art, the unit load coordination control method has the advantages that unit operation economy is improved and energy saving and emission reduction are realized.
