| Summary: | The paper proposes algorithms for calculation of transformer and autotransformer resources and control of thermal condition of windings using hardware and software of automatic control systems of technological processes at substations.The given software-hardware realization furnishes substation operational personnel with the design data on current resource wear of turn insulation of transformer and autotransformer windings that makes it possible timely to control technical conditions and take decisions pertaining to their further operation or execution of preventive maintenance or reconditioning works. Possibility to construct daily equivalent rectangular load curves of transformers and autotransformers and calculate temperature diagrams of the most heated winding point on the basis of load curves permits to organize current control over temperature and load operational modes, optimization of these modes, more efficient operation. |
