The research set the following goals:Choice of main electrical equipment.Choice of main electrical scheme of power plant.Choice of switching equipment for all voltage classes according to the calculation of short circuit currents.Examination of successful self â start of electric motors of own needs.Calculation of time value, which is needed to start the most powerful electric motor of own needs.The choice of main electrical equipment of SRPP, such as generators, power transformers, auto â transformers and lines, was done according to initial data. Moreover, the main electrical scheme was chosen for this power plant. The calculation of short circuit currents for specific parts of electrical scheme was made.The study resulted into the choice of switching equipment for every voltage class of power plant, cables for electric motors of all output categories in the system of own needs. Furthermore, he examination of successful self â start of electric motors in the system of own need was made as well as the calculation of time value, which is needed for a successful start of the most powerful electric motor. Finally, the value of antiphase switching current in a transition between working and backup power supplies was examined. |
