Abstract

The goal of this dissertation thesis is to design an atypical solution of substation with regard to the reliability of elektricity supply. Substation design is very cmoplex topic and to reach the best solution compromises must made along with consideration of input requirements. Unlike standard substation the substation for VŠB-TUO has non-standard requirements in terms of construction and functionality requirements. The substation is going to be used for various experimental measuring, tests and for educational purposes, which will require appropriate modifications. Design itsel consists of several steps, which had to be done before verifying the reliability of the electricity supply. The deviation form the standard substation design took place right from the start, where due to unusual dimensions of space for installation of substation, was necessary to change layout of devices from originally intended air-insulated substation. Development was also done for safety interlocks, which must ensure optimal operation of the substation and safety of people against injury and take into account the functionality of the substation, because limiting the operation of the substation is not desired. Due to non-standard power supply of the substation, current measuring transformers had to be parameterized and custom-made and later installed into the substation. Reliability calculations were performed for two variants of the layout of the substation, which was designed with reliability in mind. As part of the thesis, supporting documents and tests descriotion, which will be used by staff for proper control of the substation and verification of its functionality.
