In order to maximize the availability of HVDC installations and therewith secure power supply, it is highly recommended to maintain critical infrastructure on predetermined intervals and / or condition based.

Furthermore, in case of unplanned outages, emergency services should be at hand to bring assets back in operation as quick as possible.

Customers benefit from increased reliability of HVDC installations and minimized risk for unplanned outages, the increase of cost effectiveness, due to wear reserves used to full capacity.

The change of worn parts will be done during projectable shutdowns throughout granting sufficient lead time.

Safety, reliability, and availability for FACTS throughout the entire lifecycle

In times with growing bottlenecks, uncontrolled load flows, and instabilities due to the liberalization of the energy market and the increasing share of volatile renewable energies, TSOs have to make sure that their FACTS installations are working at their best to enhance grid stability and power quality. Regular maintenance, health and security checks, modernization, and retrofit as well as many other services are needed to ensure the safety, reliability, and availability of your FACTS installation throughout the entire lifecycle. That's what Siemens Energy is committed to.

At Siemens Energy, we provide you with all kinds of comprehensive services for FACTS solutions and contribute professionals with many years of experience and qualifications in the utility and infrastructure industries. You benefit from a maximized lifetime of your FACTS station, minimized downtimes, and unpredictable expenses during offline maintenance activities. You also secure the highest availability and reliability with a safe investment. Furthermore, having your FACTS managed, operated, and maintained by our experts allows you to focus on your core businessactivities. You also secure the highest availability and reliability with a safe investment. Furthermore, having your FACTS managed, operated, and maintained by our experts allows you to focus on your core business.

Is your FACTS installation ready to tackle the security challenges of digitalization?

Digitalization changes our energy systems. It offers great prospects and new business opportunities, but also harbors challenges in terms of cyber security. Cyber threats that endanger a stable operation can include attacks on communication between FACTS devices, on time- and synchronization-based control algorithms, and malicious sending of incorrect operational data. All these attacks can and should be prevented in advance. Even without a direct Internet connection, manipulated IT devices and the engineers’ and maintainers’ laptop also pose risks. To protect FACTS, we offer comprehensive cyber security support and services based on an in-depth defense concept. We identify your technical vulnerabilities, recommend appropriate security measures, and carry out their implementation. Our services for cyber security include:

Consulting regarding e.g. requirements, evaluating the own status quo and recommending the resulting security measures
Patch management (three service levels)
Security reviews, penetration tests and incident handling.

Cyber security services for FACTS you can count on

Cyber threats are increasing with serious consequences for companies and communities worldwide. Critical infrastructure, such as power transmission systems, is increasingly becoming the main focus.

Today, IT systems are the foundation of critical processes for most companies. This leads to significantly increased risks of being attacked by hackers or viruses, and patching software weaknesses is not a onetime task but an ongoing endeavor throughout the system’s lifetime. For these reasons, Siemens Energy has developed a comprehensive cyber security service portfolio for FACTS to support you.

Health check on-site condition assessment

Knowing the condition of your FACTS installation is a prerequisite to running them in a reliable and optimized way and to wisely spend your maintenance budget on the components that need the most attention. Siemens Energy health checks for FACTS provides you with a sound basis for a targeted maintenance strategy. It extends from reviewing existing documents and carrying out the on-site assessment to fixing minor defects and failures, compiling reports, and presenting findings and recommendations.

Preventing failures is less costly than fixing them. That’s why we recommend scheduled off-line maintenance activities for the entire system. The FACTS station will normally be shut down for a period of one to three consecutive working days. To support and advise your maintenance personnel, Siemens Energy provides you with a FACTS specialist as on-site supervisor. The FACTS specialist will also support you in case of any difficulties including failure analysis if needed.
