变压器的继电保护方法、装置、风力发电机组及存储介质

本申请公开了一种变压器的继电保护方法、装置、风力发电机组及存储介质，涉及电路保护技术领域，该方法包括：对变压器输出的电流进行低定值段的保护及励磁涌流检测；在电流大于或等于低定值段的预设保护值时，若电流为励磁涌流，则基于预设高定值对励磁涌流进行高定值段校验；若励磁涌流大于预设高定值，则确定励磁涌流为故障电流，并开启过流保护。在本申请中，利用低定值段识别出所有的励磁涌流与故障电流，且仅对故障电流进行过流保护，以避免因为误判励磁涌流导致误跳闸，再利用高定值段，对所有被识别为励磁涌流的电流进行校验，从中确定被误识别为励磁涌流的故障电流，并开启过流保护，以提高真实故障时电流速断的灵敏性。 The invention discloses a relay protection method and device of a transformer, a wind generating set and a storage medium, and relates to the technical field of circuit protection, and the method comprises the steps: carrying out the protection of a low constant value segment and the detection of excitation surge current on the current output by the transformer; when the current is greater than or equal to the preset protection value of the low constant value section, if the current is the magnetizing inrush current, performing high constant value section verification on the magnetizing inrush current based on a preset high constant value; and if the magnetizing inrush current is greater than the preset high constant valu
