Distance between substation and communication base station

How are substation design requirements determined?

Substation design requirements will be determined by the following studies. A substation ensures reliable power transmission to system loads. The current carrying needs of the new substation (or) switching station are determined by load flow studies while all lines are in & while selected lines are out for maintenance.

How many mobile substation units should a substation have?

Two (or more) units may be the best answer on some systems where the variety of substations is great. The design of many mobile units is restricted by the opposing requirements of larger transformer capacity, higher primary voltages, and highway limitations on physical size and weight.

What is a transmission substation?

A transmission substation is a combination of switching, controlling, and voltage step-down equipment arranged to reduce transmission voltage to subtransmission voltage for distribution of electrical energy to distribution substations. Transmission substations frequently have two or more large transformers.

What is a substation system?

These systems consist of a central host computer system at the energy control center, referred to as a master station, and RTUs located in the substations. There is a trend toward increasing intelligence at the substation level (see Chapter 14, Substation Automation) where the traditional RTU is being replaced with IEDs in a LAN arrangement.

Why do substations need a communication network?

Substation equipment and control centers need efficient communication networks to share data and control. Substation design architecture requires dependable communication protocols like IEC 61850, DNP3, or Modbus for interoperability, data integrity, & cybersecurity.

What is a substation structure design guide?

The American Society of Civil Engineers (ASCE) is currently developing a substation structure design guide that will discuss in greater detail various structure types, loading criteria, deflection criteria, methods of structure analysis and design, and structure connection to foundations.
