Problems solved by technology

However, this method cannot determine whether the control program controls the cooler correctly and effectively. During the transformer maintenance period, the newly optimized control program must be downloaded to the on-site controller for relevant tests, and it can only be put into operation after passing the test.
In this way, it will take up more maintenance time and affect power production
If the test results are not satisfactory, it may be necessary to re-modify the control program and repeat the test, which will have a greater impact on power production

Abstract

The invention discloses a transformer forced oil circulation water-cooling cooler simulation control system. The system comprises a cooler controller, the cooler controller comprises a controller switch quantity input module and a controller CPU module; the controller switch quantity input module is connected with each of a transformer load simulation module, a transformer temperature simulation module, a cooling water simulation module and a cooler fault simulation module; the controller switch quantity input module is used for receiving a state signal required by the simulation controller. The simulation control system provided by the invention aims at solving the technical problems that much overhauling time is occupied and the electricity production is influenced since a newly optimized control program needs to be downloaded to the cooler controller in the field running to perform testing in the transformer overhauling period when determining whether the control on the cooler by the control program is accurate and effective.

Description

Technical field [0001] The technical field of transformer detection of the present invention specifically relates to a simulation control system and method for a forced oil circulating water-cooled cooler of a transformer. Background technique [0002] The cooling system of large transformers often uses forced oil circulation water-cooled coolers. This is a forced oil circulation cooling method using water as the cooling medium. In the transformer using this cooling method, the oil tank is not equipped with a radiator, but a water cooler connected to the oil tank is installed outside the transformer, including an oil pump, a water valve, and a cooler pipe. Inside the water cooler, there is cooling water controlled by a water valve. The hot oil flows through the outside with the help of an oil pump. The cooling water takes away the heat of the oil and then drains it from the drain pipe. The hot oil is cooled and returned to the transformer tank to lower the transformer. The inte...
