Fixed value protection setting method comprehensively considering new energy and flexible power transmission fault characteristic

The invention discloses a fixed value protection setting method comprehensively considering new energy and a flexible power transmission fault characteristic. The method comprises the following steps of 1) acquiring power grid models including the new energy and flexible power transmission equipment, parameters and mode data from a setting software database; 2) according to rated power information of power generation equipment including wind-power, photovoltaic, photo-thermal and conventional power generators, setting corresponding generated output and a voltage, according to characteristic parameters of wind-power, photovoltaic, photo-thermal new energy equipment and flexible power transmission equipment including a UPFC and flexible direct current power transmission, setting corresponding operation data and forming a section which can be used for trend calculating; 3) carrying out trend calculating, and if calculation is failed, returning to the second step and readjusting the generated output, the voltage
