Abstract
This paper considers installation of a flexible AC transmission system (FACTS) device on the 500 kV line of substation (SS) Belozerskaya - SS Vologodskaya of the United Power System of Center. Three FACTS devices in normal operation mode were modeled: a static reactive power compensator (STATCOM), a static synchronous series compensator, and a unified power flow control system. The obtained results are summarized in Table, which substantiates the choice of the best compensation for the Belozerskaya Vologodskaya line.
Highlights
Development of electric power complex is one of the most important tasks of the Russian Federation nowadays
The conducted modeling shows that each flexible AC transmission system (FACTS) device compensates reactive power in different ways
The values given in Tables allow one to choose the best compensation for the 500 kV line SS Belozerskaya - SS Vologodskaya
Summary
Development of electric power complex is one of the most important tasks of the Russian Federation nowadays. The first item accounts for the highest electrical energy consumption, since reactive power arises in wires during transmission, and its loss is greater for the longer line This problem can be solved if one includes devices that compensate it during undervoltage or overvoltage in the line. SSSCs are series-connected FACTS devices based on a converter based on voltage source and they can be considered as a perfect type of series compensation, in a similar way STATCOM is more advanced equipment than static reactive-power compensator. These includes the following tasks: 1) To model a power line and analyze its output active and reactive power, as well as voltage. The 500 kV line SS Belozerskaya - SS Vologodskaya of UPS Center was selected to install the devices
