Pełniejszy materiał źródłowy / excerpt
A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and the consumer, electric power may flow through several substations at different voltage levels. A substation may include transformers to change voltage levels between high transmission voltages and lower distribution voltages, or at the interconnection of two different transmission voltages. They are a common component of the infrastructure. As of 2022, there were approximately 55,000 substations in the United States. Substations are also occasionally known in some countries as switchyards. Substations may be owned and operated by an electrical utility, or may be owned by a large industrial or commercial customer. Generally substations are unattended, relying on SCADA for remote supervision and control. The word substation comes from the days before the distribution system became a grid. As central generation stations became larger, smaller generating plants were converted to distribution stations, receiving their energy supply from a larger plant instead of using their own generators. The first substations were connected to only one power station, where the generators were housed, and were subsidiaries of that power station.

An electrical grid (or electricity network) is an interconnected network for electricity delivery from producers to consumers. Electrical grids consist of power stations, electrical substations to step voltage up or down, electric power transmission to carry power over long distances, and finally electric power distribution to customers. In that last step, voltage is stepped down again to the required service voltage. Power stations are typically built close to energy sources and far from densely populated areas. Electrical grids vary in size and can cover whole countries or continents. From small to large there are microgrids, wide area synchronous grids, and super grids. The combined tran…

A linear programming joint optimization model of overnight train timetabling and maintenance planning on high-speed railway.. Maintenance activities on high-speed railway (HSR) facilities are essential for ensuring operational integrity, typically scheduled during the overnight window (0:00-6:00) to avoid disrupting daytime services. This practice, however, conflicts with the operation of overnight trains. To address this issue, this study develops an integrated optimization model for joint train timetabling and maintenance planning. First, we compare two minimum maintenance units (station sections and power supply sections) and justify the selection of the latter based on its superior appl…
