A helium flow control system and method for a high temperature gas-cooled reactor having an incremental adjustment function. The method comprises the following steps: 1) calculating a hot helium temperature correction value for hot helium temperature PID adjustment; 2) calculating a power correction value for power PID adjustment of a unit; 3) calculating a helium flow correction value for helium flow PID adjustment; and 4) performing three-element control according to the hot helium temperature correction value for hot helium temperature PID adjustment, the power correction value for power PID adjustment of the unit, and the helium flow correction value for helium flow PID adjustment, and then controlling the reactor according to the result of the three-element control. The helium flow control system and method for the high temperature gas-cooled reactor having an incremental adjustment function can quickly track the change trend of control variables, correct the outputs of the control variables, and meet th
