The invention discloses a grid security and stability control method involved in wind power plant benefit fairness, and belongs to the technical field of power system operation control. An online security and stability prewarning system is organically combined with a security and stability control system, a grid operation work condition is calculated and analyzed on line, a key transmission section, the transmission limit of the key transmission section, a controllable wind power plant set and sensitivity of the controllable wind power plant set to the key transmission section are refreshed, then a generator tripping control range is determined in real time according to a sensitivity sequence, and generator tripping controlling quantity is averagely distributed according to contribution to security and stability problems in the selected control range. According to the method, requirements of a wind power base for safe and stable operation are met, meanwhile, requirements of the wind power plant for fair benefits in emergency control are met, and the refinement level of wind power emergent control is improved.
