Transformer substation switching control system and method

Abstract

The embodiment of the invention discloses a transformer substation switching control system and method. The control system comprises a position judging device, a PLC, a power supply air switch and a switching driver, wherein the position judging device is electrically connected with the PLC and is used for judging the states of a line switch and a knife switch in primary equipment, the PLC is used for judging whether the knife switch has an operation condition according to the judgment result of the position judging device, if the PLC judges that the knife switch has the operation condition, the PLC controls the power supply air switch to be closed and controls the switching driver to carry out switching operation, otherwise, the PLC executes interruption operation, and the power supply air switch is electrically connected with the switching driver and is used for controlling whether the switching driver is connected with a power supply signal or not. According to the embodiment of the invention, the circuit switching operation is automatically executed through the PLC control program, so that the automation level of the transformer substation can be improved, misoperation caused by human factors can be better avoided, the operation cost is saved, and safe and stable operation of the transformer substation is ensured.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of intelligent substations, in particular to a substation switching control system and method. Background technique [0002] Smart substations are an important part of smart grids. The focus of development in the field of power transformation is smart substations. Smart substations will play a pioneering role in the construction of smart grids. The switching operation of primary and secondary equipment is an important link that restricts the development of smart substations. The switching operation involves the transition of the state of electrical equipment, which generally starts with the dispatching order. From the operator receiving the dispatching order to the completion of the entire operation process, there are danger points in every link; due to the variety of substation equipment and many influences during the operation process Factors, so dangerous points generally exist in t...

Problems solved by technology

Whether it is because the operating personnel did not operate item by item according to the dispatch order, strictly abide by the switching operation process, or out of carelessness, they did not rigidly execute the operation ticket, or due to insufficient technical level, they operated blindly because they knew little about the equipment to be operated. etc., may lead to misoperation, and in serious cases will endanger the life of the operating personnel and the safety of the entire power grid
