Electricity generation. An electrical substation is a subsidiary station of an electricity generation, transmission and distribution system where voltage is transformed from high to low or the reverse using transformers.
Power Substations HV/MV/LV Guides. Simulation models have been developed for assessing earthquake performance of transmission lines that can be used to forecast the following types of information: for a given earthquake, what is the damage to the substations or the number of transmission towers likely to collapse; what is the forecast reliability of a circuit, from end-to-end.
Distribution substation A distribution substation transfers power from the transmission system to the distribution system of an area. The input for a distribution substation is typically at least two transmission or subtransmission lines.
Distribution voltages are typically medium voltage, between and 33 kV depending on the size of the area served and the practices of the local utility. Abstract-This paper focuses on the reliability evaluation of modern substation automation systems. Such systems include digital substations of the future.

Chapter 3: Enabling Modernization of the Electric Power System Technology Assessments Cyber and Physical Security reliability, ease of operation, and to meet consumer high voltage direct current, flexible alternating current transmission system, integrated solutions) – CHAPTER 4 SUBSTATION CONFIGURATION RELIABILITY ESTIMATIO N BY SUCCESSFUL PATH METHOD Substations are integral parts of a power system.
They are important links between the generating station, transmission systems, distribution systems and the loads at consumer level.
The electrical voltage is stepped up and down to higher and lower voltage. Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical walkingshops.com interconnected lines which facilitate this movement are known as a transmission network.
This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution.
