Substations are integral components of power grids. They connect grids of differing voltage levels. Siemens is making them digital and preparing them for the future.
Only through digitalization it will be possible to master the transformation to a multi-directional energy system. To ensure that the digital transformation will succeed, you need the right strategy – and an experienced partner.
The systems for power generation, transmission, and distribution are undergoing a radical transformation. The traditional model, in which electrical energy is generated and distributed centrally, is making way for flexible systems into which renewable energy sources, decentralized generators, prosumers, and power storage solutions need to be integrated. More than ever, grid operators are relying on technical systems that are prepared for these changes – on products and solutions with the Future built in.
As integral parts of power grids, substations essentially represent the heart of the power supply. As such, they take on a key position in this development. When it comes to the automation, monitoring and protection of a substation, digital technology really comes into its own. Siemens offers grid operators an integrated portfolio of products and solutions which can be used to make substations consistently digital and capable of handling anything that comes their way.
Our experience in infrastructure and software uniquely positions us as your end-to-end digitalization partner.
The most important aspects
Siemens is a pioneer in the development and integration of information and operational technology (IT/OT) and associated services. The primary objective of the IT/OT coupling is to help utilities to increase the safety and efficiency of their grids.
Our medium for this coupling is MindSphere, the cloud-based open IoT operating system. MindSphere makes it possible to connect your digital substation to the digital world. You can use practically unlimited data volumes of intelligent components. You gain valuable knowledge about your digital substation and much more.
You can optimize your grid management by linking the most important components of your digital substation to MindSphere. The data from your assets – protection devices, devices for substation automation, field devices and sensors from Siemens or from other manufacturers – is securely encrypted and transmitted to MindSphere. This is backed by a high-performance state-of-the-art server and computer infrastructure.
Continuous security patching
The applications that create added value and pave the way for new business models feed into MindSphere from the other side. These applications can come from Siemens as well as from you or from your end customers. They make it possible to optimize your grid management. Examples include simpler asset management as well as an option for continuous security patching in which your cyber security tools always receive the latest updates automatically. You no longer have to worry about making the updates yourself. Once you know that the majority of cyber attacks are successful only because operators have not updated their systems with available patches, the significance of this benefit quickly becomes clear.
Siemens as a partner
Siemens offers a 360° portfolio for digital substations. For grid operators, technical and consulting expertise add up to a unique form of value added: the value added Future. This comprises the benefits of enduring technology and maximum economy but also a feeling of security and confidence in mastering the transition that comes with a Siemens digital substation – no matter what the future brings.
Benefit from comprehensive expertise that combines global market insights with technological know-how. With Siemens, grid operators receive everything from a single source: products and solutions, qualified advice and services. You have only one solutions provider who bundles all topics. This saves time and optimizes the results.
The smooth and cost-effective operation of your system requires an overall concept made up of cyber security and physical security. Around the world, Siemens offers proven solutions for end-to-end security that combine protection against cyber attacks, access control, building automation, and fire safety.
With MindSphere, the cloud-based open IoT operating system from Siemens, grid operators also benefit from the advantages of digitalization. MindSphere connects your digital substation to the digital world – for significantly greater availability and efficiency.
As a global player, we have a presence in nearly 200 countries around the world and, as such, we are literally very close to all of our customers. We are familiar with the peculiarities of the markets as well as their rules, requirements, and standards. Plus: On request, you can receive tailor-made support for the financing of your projects.
