Investigating Dispatching Control Centers And Principles OfOperation Of SCADA Systems In Monitoring Power Networks

The power network (transmission and distribution) in any country plays the main role in deliveringelectricity from power plants to consumption centers. Meanwhile, the visibility of all networkparameters is very important. SCADA system is used for visibility and online modeling of the network.In this article, an introduction to dispatching and the SCADA system is given at the beginning. In thenext section, the control of power network parameters including frequency and voltage is given. In thenext section, dispatching centers are introduced. Considering the extent of the network, maintaining thestability, stability and reliability of the network in supplying electricity to consumers is considered animportant principle, which is the responsibility of the dispatching center, in fact, the dispatchingmanages the network and by planning and conducting side studies and guidance Extraction from theproduction and transmission network guarantees the stability and stability of the network, in order tomore closely monitor the production, transmission, super-distribution and distribution sectors accordingto the importance of these sectors, the dispatching center is divided into smaller subsets according to thegeographical area. to be In the following parts, the necessity of dispatching centers, the structure of adispatching system and its equipment, the duties and officials of the dispatching control center and themethods of sending information in the power grid are described. At the end of the article, the conclusionis given.
