Embodiment Construction
[0051] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0052] Such as figure 1 , providing a wind farm reactive voltage optimal control method, characterized in that: the method includes the following steps:
[0053] Step 1: The wind farm data monitoring system receives the wind farm grid-connected point voltage command issued by the dispatching system And collect the real-time operation information of each control unit;
[0054] Step 2: Compare the real-time voltage V of the grid-connected point PCC and the grid-connected point voltage command of the wind farm Determine whether the reactive capacity required by the wind farm is inductive reactive power or capacitive reactive power, and then determine the respective reactive output limits of wind turbines and parallel compensation;
[0055] Step 3: Establish the reactive power and voltage optimization control model of the wind farm;
[0056] Step 4: Optimi...
