The invention provides a power load state identification method, system and device, and a medium. The method comprises the following steps: obtaining net power request values of a plurality of continuous sampling moments and an actual power value in a neighborhood time range of each sampling moment; if the change quantity of the net power request value is within a preset change range, determining a power control error according to the net power request value and the actual power value, and comparing the power control error with a preset error threshold value, so as to control the actual power value when the power control error is smaller than the preset error threshold value within a preset first time limit. And determining that the power load state of the fuel cell engine at the current sampling moment reaches a steady state, the net power request value variation being the difference between the net power request value at the current sampling moment and the net power request value at the previous sampling moment. According to the invention, the state identification accuracy and the anti-interference capability can be effectively improved.

    本申请提供一种功率负荷状态识别方法、系统、设备和介质,该方法包括:获取连续多个采样时刻的净功率请求值以及每个采样时刻邻域时间范围内的实际功率值;若净功率请求值变化量在预设变化范围内,则根据所述净功率请求值和所述实际功率值确定功率控制误差,并将所述功率控制误差与预设误差阈值进行比较,以在预设第一时限内所述功率控制误差小于所述预设误差阈值时,确定当前采样时刻燃料电池发动机功率负荷状态达到稳态,其中,所述净功率请求值变化量为所述当前采样时刻与前一采样时刻的净功率请求值之差。本申请可有效提高状态识别准确性以及抗干扰能力。
