Abstract
To solve the common problem that the traditional primary frequency regulation control strategy is not able to achieve sufficient primary frequency regulation capability and is easy to cause intense oscillation of frequency modulation devices,a primary frequency regulation control strategy with“fast-moving and delayed-returning"or“fast-moving and slow-returning"technology is proposed based on the j udging of frequency difference and the blocking of inverse regulating action.The proposed strategy can provide more frequency regulation electric power by blocking or limiting the inverse frequency regulation effect of power grid,which makes the primary frequency regulation better coordinated with the secondary frequency regulation,thus improving both the elimination speed of power grid frequency difference and the quality of power grid frequency control. Furthermore,a counter-measure against power overcorrection or power j umping problems in practical applications is proposed by setting appropriate control parameters such as the frequency regulation gain.In the end,in order to prove the effectiveness of the proposed strategy,both the traditional primary frequency regulation control strategy and the proposed strategy are applied to two coal-fired power generating units.Experimental results show that the proposed strategy can provide more frequency regulation electricity for power grid as well as reduce generator wear caused by frequency regulation,thus benefiting both power grid and generator units.关键词
