How do you determine a substation?
Determine the substation size and total footprint required (with equipment), including transmission right of way (ROW). Determine substation configuration (Single Bus, Main/Transfer Bus, Ring Bus, etc.). Allocate required funds for real estate purchase, planning, engineering, construction, implementation, etc..
What is a Generator Substation & how does it work?
Generating substations step up the voltage from the generator's lower voltage to a higher voltage which is more economical for transmitting electric power over longer distances with less power losses caused by the impedance of transmission lines.
How does a utility plan a new power substation?
The basic steps a utility may perform in planning and implementing a new substation are: Conduct planning meetings for the new power substation. Perform load flow power studies. Determine the substation size and total footprint required (with equipment), including transmission right of way (ROW).
What is an electric power substation?
For the most part, electric power substations are viewed as the most integral part of a power utilities' electric system, with electric systems being comprised of power generation, transmission, and distribution systems. (See A Basic Explanation Summary of How the Electric Power Grid Works)
How to number power transformers in a substation?
Where the layout of the substation is not constrained, the preferred power transformer numbering sequence is to be such that when standing on the transformer runway facing the higher voltage area, the main transformers are to be numbered 1, 2, 3, 4, etc. from left to right.
What voltage does a distribution substation operate at?
Distribution substations operate mainly at voltage levels 33kV and below. When a utility prepares to add a new power substation to their electric grid, it's usually because the electric load growth in their area has increased by consumers – new growth in businesses, industries, residential, etc.

What is a parallel power supply?
Parallel power supplies refer to a configuration where multiple DC power supplies are connected in parallel to increase total output current. Each power supply shares the current load, ensuring that no single unit is overloaded. Higher Current Output – Allows for increased power delivery by combining the output of multiple units.
Can power supplies be connected together for parallel operation?
The power supplies can be connected together for parallel operation to increase the output current. See Figure 1 below. To achieve this, it is important that the output voltages of both power supplies must be within 25mV difference of each other.
Can a DC power supply be connected in parallel?
DC power supplies may be connected in parallel for either increased power output or improved redundancy. When connected in parallel, output current will be 2X of that of one individual power supply.
Is it possible to parallelize a power supply?
Typically, identical supplies are used when configuring them in parallel, given the challenges associated with efficiently aligning different power supply configurations. Nonetheless, it is feasible to parallelize supplies with matching output voltages while having non-matching maximum output currents.
Can power supplies be connected in series?
Power supplies can be connected in series to increase the output voltage as shown in Figure 5. Only power supply from the same product series and with same rated output current should be used. The maximum load current should not exceed the smallest rated output current, when selecting power supplies with different current ratings.
What happens when a supply is connected in parallel?
As mentioned previously, when connecting the outputs of supplies in parallel, each supply provides the required voltage, and the load current is shared between the supplies.
