Substations interconnect different voltage levels and are the critical link between transmission, distribution and consumption. Primary equipment like power transformers, circuit breakers and disconnect switches located in the switchyard of the substation transform, protect and manage the grid power supply.
A digital substation using fiber-optic cables for communication digitizes data related to the process parameters being measured using conventional or nonconventional instrument transformers (NCITs) and a merging unit. Using less copper makes the digital substation simpler, more compact and more eficient. Figure 2. Digital substation architecture.
With a focus on greener power, improved eficiency and the adoption of smart-grid technologies, utility companies are upgrading from conventional substations to digital substations. Substations interconnect different voltage levels and are the critical link between transmission, distribution and consumption.
In most countries, less than 10 % of transformer substations and ring-main units (RMU) are monitored and controlled from remote. The rapid increase in distributed energy resources today is impairing the power quality of the distribution network. That is why system operators need to be able to respond quickly in critical situations.
Abstract Substation and its communication architecture play an important role in maintaining high reliability, and availability of the power supply. Due to the proliferation of multi-vendor IEDs (Intelligent Electronic Devices)
A prerequisite for this is the integration of the key ring-main units as well as the volatile decentralized wind and solar generation into the energy management system, and thus into the communication network of the
