Expert consulting for optimized total cost of ownership Finding the optimal solution means making a decision between two basic approaches: an system-oriented or a more product based approach with product-related tools. Both approaches have the advantage of an object-oriented engineering where every data point needs to be entered once only. That is why Siemens attaches great importance to thorough planning of the systems. All projects are developed in close cooperation with the customer right from the beginning. Siemens share its expertise gained from numerous projects and years of successful project realization. The entire engineering process can thus be tailored to suit the customer s need. This pays off through optimized total cost of ownership: costs for the initial project, for follow-up projects, for operation, and for migration are mini mized. 5
How can my infrastructure live up to new challenges? All assets always seamlessly up to date. One of the most difficult tasks in modern energy automation is to delicately balance the fast-paced world of digital technology and electronic devices with the demands of a business sector whose secondary technology knows average product life cycles of 15 years or even more. Primary technology, on the other hand, with its average product life cycle of about 40 years, makes for future challenges that are trendsetting from today s point of view. Next grid generation The evolution of grid structures and the emergence of the Smart Grid poses new challenges for power generation and grid operators. Intelligent power transmission and distribution calls for more online data and shorter reaction times. This requires intelligent applications, which enable the autonomous performance of network functions. On the other hand, monitoring all essential network components and resources becomes more and more important. It is essential for the protection of the systems from faults as well as for the optimization of utilization of network asset capacity. Reserves for the things to come Siemens ENEAS system solutions always put you ahead of the field: they keep all options open for the evolutionary growth of energy automation systems. The integration of new systems within a given infrastructure can be performed without 6
any problems. Open protocols and interfaces also make possible smooth future system extensions, refurbishments, partial replacements, migrations, as well as the implementation of entirely new systems. This saves valuable time and resources today and tomorrow. The open tools and database, as well as generated data point lists, can be made further use of for years to come. Format adaptations can be performed without difficulty. Due to the longer life cycle of primary technology, the object-oriented database, i.e., the parameterization, is oriented on the primary technology. Thus, parameterization data can be retained unchanged or reused whenever the secondary technology is replaced. All protocols under control Thanks to Siemens long-standing firsthand experience and technical expertise in the field of energy automation and system integration, interface problems are a thing of the past: Siemens ENEAS system solutions are able to handle most of the world s relevant data protocols. Third party protocols can therefore be embedded easily, thus supporting the avail ability and reliability of the entire system. Moreover, with Siemens ENEAS system solutions as a common hub, different generations of equipment, even from other vendors, can interoperate seamlessly. 7

As a leading supplier of energy automation products and systems, Siemens has accumulated many years of reliable experience in project planning and implementation with an appropriate consideration of Capex (capital expenditure) and Opex (operational expenditure). 8
What s the peace of mind solution for energy automation systems? Reliable operation All Siemens ENEAS system solutions are developed with the full scope of energy automation tasks and purposes in mind. Siemens energy automation products that have already proven their reliability are the basis for all Siemens ENEAS system solutions. All solutions integrate smoothly into any energy automation infrastructure. This translates into shortest possible downtimes and maximum personal safety. In addition, all solutions can be mapped and matched to the operational procedures of the network operator. All these factors taken together make for a reliable operation under all circumstances at a high degree of operational and personal safety. Optimum security Earlier energy automation systems used to operate in isolated environments with proprietary technologies. But the adoption of commercially communication tech nologies like TCP/IP causes the energy sector to become increasingly connected and interdependent. This results in attractive targets for attacks. Such cyber attacks can have significant impact on the entire system. That is why Siemens ENEAS system solutions comprise extensive hardwarebased and software-based state-of-theart protection against unauthorized system access. 9

International standards (IEC 61850, 60870, 61970, 62351 ) ENEAS substation Substation automation and protection Digital substation automation systems Distribution automation Telecontrol systems Protection systems Communication ENEAS communication network Communication network Communication systems SDH or IP technologies Powerline carrier, teleprotection systems Wireline and wireless systems The entire scope of energy automation under control Infusing intelligence into grid structures through state-of-the-art energy automation devices paves the way for Smart Grids. Siemens ENEAS solutions provide: Substation automation and protection Digital substation control is mainly based on distributed devices and provides a multitude of functions for data acquisition, control and monitoring, protection, and communication. Classical telecontrol, mostly used for small substations and refurbishment, and focused on mere information transmission, follows a rather centralized approach. These two modes of substation automation are increasingly growing together. 10 On the high and medium voltage levels, protection systems play an important role. They are used to protect expensive assets, for example switchgear, transformers, or cable outlets. Different grid structures and changing operation modes call for more sophisticated protection schemes to ensure selectivity. Distribution network automation deals with the interface between the medium and the low voltage level. Reliable communication and auxiliary power supply are most important for these network nodes. The same goes for the use of small, flexible telecontrol units for both substations and overhead line networks. Communication network The mostly heterogenous communication networks of utilities with gaps in capacity and bandwidth need to be migrated to a Smart Grid communication network with IP/Ethernet connectivity down to the distribution network and the customer s premises. For special protection requirements in energy transmission networks (distance-/differential protection, phasor measurement), SDH networks are mandatory. Also, due to investment protection reasons, serial interfaces will continue to play a role in the next future. For these complex communications requirements, Siemens supplies tailored, ruggedized communication network solutions for fiber optic, powerline, or wireless infrastructures and based on standards. Naturally, this also includes a full range of services, from communication analysis to the operation of the entire solution.

Capacity utilization, availability, and power quality can only be optimized on the basis of precise data. Moreover, operation data analysis by condition monitoring paves the way for preventive maintenance. It allows for the logging of the overall quality of supply and of grid pollution caused by consumers. The systems are supported and controlled by fault analysis, fault location, and monitoring. Such measures become more and more important in view of the public regulators tendency to impose more and more quality specifications on network operators and new business models in which power quality is an integral part of the contract. Control center The control center is the place where all pieces of the entire network come together. All energy automation data is merged, processed, and visualized here, while the staff monitor and control entire grids. The control center is the management as well as for all analyses and optimization of transmission and distribution networks. Siemens has systems and applications available for all these tasks. Smart metering The next generation of meters combines sophisticated metering functions, and supports the management of distribution networks. Developed to suit the new challenges of the liberalized energy market, it allows distribution network operators to optimize essential key processes and offer new services like flexible tariffs to their customers. Industrial customers may also provide data for load forecasts which further facilitates advance planning and network capacity optimization for the utility. 11
