Threshold value calculation method and device, equipment, storage medium and program product

The invention relates to a threshold value calculation method and device, equipment, a storage medium and a program product. The method comprises the following steps: determining system operation data respectively corresponding to a plurality of possible DC power levels of a DC system connected with a converter station; for each possible direct current power level, determining a reactive power threshold value according to system operation data corresponding to the possible direct current power level; wherein the reactive power threshold value corresponding to each possible direct current power level is used for switching an alternating current filter by a power system according to the reactive power threshold value corresponding to each possible direct current power level when the converter station operates normally. By adopting the method, the reactive power threshold value switched by the alternating-current filter under each possible direct-current power level can be accurately calculated. 本申请涉及一种门限值计算方法、装
