Method and device for calibrating settlement meter of steam turbine generator

The invention relates to the technical field of nuclear power overhaul, in particular to a settlement meter calibration method and device of a steam turbine generator. In the embodiment of the invention, one measuring unit in all measuring units of the settlement meter is used as a reference measuring unit, all measuring units except the reference measuring unit are used as to-be-calibrated measuring units, and the to-be-calibrated measuring units are calibrated based on the reference measuring unit. Therefore, the same liquid level measurement value is output under the condition that the measurement units have the same liquid level distance, and the accuracy of monitoring data of the settlement meter is improved. On the basis, a plurality of turbine generator units can be monitored through one calibrated settlement meter, intermittent measurement of the settlement meter is realized, and the monitoring cost is further reduced. 本申请涉及核电检修技术领域，特别是涉及汽轮发电机的沉降仪标定方法及其装置。在本申请实施例中，通过将沉降仪的所有测量单元中的一个测量单元作为基准测量单元，将所有测量单元
