The topic of the final qualifying work: "Implementation of models of relay protection system of electric power facilities".This work is devoted to the development of a model of the relay protection system and automation of electric power facilities and the identification of prospects forthe use of models. As well as the design of the 330/110/35/6 kV substation. As part ofthe work, the following tasks were solved:1. selection of the structural scheme of the PS and the main equipment;2. calculation of short-circuit currents at characteristic points of the circuit;3. selection of switching devices, conductors, measuring current and voltagetransformers.4. Methodology of software and technical implementation of the RPA model.5. Development of the relay protection system model.6. simulation of the actions of relay protection system devices in case of emergency.A model of the relay protection system for the existing facility was built. Theapplication of the relay protection system model for a node substation is considered.The main technical solutions that can be used to build the model were demonstrated,its block diagram was developed, the model was built using the graphical programminglanguage G in the LabVIEW software package.As a result, the user interface and means of observing the experiment were analyzed and created. The test operation is shown in normal mode and with some eventsrelated to the erroneous construction of the relay protection system. |
