2024年12月18日 · The Digital Substation is a term applied to electrical substations where operation is managed between distributed intelligent electronic devices (IEDs) interconnected by communications networks. It became possible by using computing technology in …

The digital substation means replacing conventional measuring equipment such as current transformers (CTs) and voltage transformers (VTs) with non-conventional instrument transformers using digitalized sensor technology. This will reduce exposure to high voltage signals.

At its core, a digital substation focuses on converting binary status and analog measured data into digital data - reliably and seamlessly. This makes data easier to transmit and share between devices and substations in real time, so it can be better utilized, processed and acted upon.

The digital substation concept promises to digitize a portion of the substation secondary system by eliminating the majority of analog secondary circuits between the instrument transformers and protective relays.

2024年3月18日 · Digital substations use modern sensors, communication networks, digital technology, and intelligent devices to monitor, control, and manage electrical assets, in contrast to traditional substations that depend on analog systems and manual operations.

As its name suggests, the digital substation brings digital technology into the heart of the substation. The digital substation focuses on digitalization of both station level and process level by converting analog measurement data and binary status information into digital data.

Digitalized substations collect valuable data from the entire power grid. This means that the heart of the power supply can also become the heart of energy data communication – and can create added value.

Digital substation solutions enable utilities like yours to satisfy the demands of the modern electricity network and address potential challenges. Hitachi Energy’s comprehensive digital substation portfolio gives you improved visibility for protection, control, and monitoring.

2024年1月22日 · Modern electronic meters are used at substations. At the same time, the devices can operate either autonomously or combined into a system (AIMS KUE – automated information and measurement system for energy resources accounting). How is a digital substation different from a conventional substation?

As power generation sources increasingly volatile, Hitachi Energy offers intelligent, and reliable grids to fulfil the power requirement of digital substations.
