Savings Potential through Transparent Energy FlowsEnergy Management in Low-Voltage Power Distribution

2

Energy Management – the Intelligent Response to Energy Demand IssuesWhether electricity, water, or gas: In view of increasing prices and a higher sensitivity towards environmental issues, energy is becoming an increasingly valuable resource, and thus an enormous challenge, especially with regard to high energy volume, maximum availability, and continuous cost reductions.

The objective of a corporate energy management system is to identify and implement energy savings potentials. Standards, e.g. the new EN16001 standard that became effective in August 2009, provide the basic conditions for the introduction of a corporate energy management system. In the future, companies will be able to obtain an energy management certification, similar to the one for quality management.

The hardware and software components of our energy management system for low-voltage power distribution make energy consumption transparent, document it, and thus support your corporate energy management.

Everything you Need for Professional Energy Management

Comprehensive Portfolio ■

Siemens offers a comprehensive portfolio of compatible hardware and software components for the implementation of an energy management that fulfills all respective customer requirements.

Transparent Energy Flows ■

The measuring devices SENTRON PAC, the circuit breakers SENTRON 3WL/3VL and other low-voltage power distribution components provide measured values and characteristics that are processed, monitored, and archived by intelligent software. The gathered data can be displayed in a structured and customized manner and makes power distribution transparent.

High Savings Potential ■

The measurement and visualization of electrical power flows and the initiatives that were derived from them, e.g. the reduction of peak loads, energetic proc-ess redesign, and guaranteed adherence to agreements with power suppliers, provide for energy cost savings of up to 20 percent.

Highest Possible Availability ■

By constantly monitoring the power distribution, it is possible to recognize problems that could lead to a failure of the installation early on, and to even address them to prevent a failure. In ad-dition, respective warning notifications, e.g. relating to timely maintenance, failures and the resulting damages may be prevented, or, in the event of a fault, quickly be located and addressed accord-ingly. This improves the availability of your power supply.

Always completely in the know due ■

to intelligent measurement methodsThe power monitioring devices and the e-counters SENTRON PAC detect and document energy values of infeeds, outgoing feeders or individual loads in a precise, reproducible, and reliable man-ner. They also provide important mea-sured values that can be used to analyze the status of the system and the power quality. To further process the measured data, the devices, due to their versatile communication capability, can easily be integrated into higher-ranking automa-tion and energy management systems.

Switching and protection devices ■

with communication capabilityThe air circuit breakers SENTRON 3WL and the molded-case circuit breakers SENTRON 3VL that are part of the low-voltage power distribution systems, are more than just switching and protection devices. They provide measured val-ues and important information for the diagnostic, fault, maintenance, or energy management by using standardized bus systems, and thus offer new possibili-ties with regard to the implementation of profitable and highly-available power distribution systems.

Integration of other components ■

into the energy management systemOther switching, protection, or measu-ring devices can be integrated into the energy management system, either via its own communication interface or its S0 interface. This way, for example, con-sumption values of non-electrical energy carriers such as gas or water, and the switching state of devices without com-munication capability can be analyzed in the energy management system.

Integrated, Professional Energy Management PortfolioCompatible hardware and software components provide efficient energy management that meets all requirements, from standard solutions to customized applications.

Requirement ■

Administrative offices such as those of universities, shopping centers, or retail chains must be able to allocate the en-ergy costs to their respective originators.

Implementation ■

Measuring devices with communication capability such as SENTRON PAC or e-coun-ters linked to power monitoring devices via impulse interfaces are installed at signifi-cant operational locations. The cost centers are defined in the cost center management function of the SENTRON powermanager and allocated to these respective measure-ment locations with their respective pricing structure.

Benefit ■

Cost center reports (automatically gener-ated or individually requested) analyze the energy consumption and calculate the charges for each originator. Energy awareness is heightened by benchmark-ing various cost centers.

Highlights

Requirement ■

For businesses with energy-intensive processes, it is important to document and analyze load peaks and high energy consumptions. On the one hand, the drawn loads affect the supply conditions, and on the other, tax savings can be realized by providing seamless proof of energy-intensive processes.

Implementation ■

Measuring devices with communication capability, e.g. SENTRON PAC are installed on some of the business’s most important loads. SENTRON powermanager archives their measured values and prepares them for further analysis.

Benefit ■

Trend analyses are able to indicate up to 16 load-defined curves, e.g. of infeeds and up to 15 outgoing feeders. The trend analysis identifies both infeed peaks as well as areas that produce the highest load on the outgoing side. After having analyzed these, consumption behavior can be modified to reduce load peaks. Power supply agreements can be re-negotiated and optimized on the basis of load flows. The documented energy consumption may lead to tax refunds.

Highlights

Requirement ■

In the industry, undesirable load peaks may occur and lead to additional pay-ments to the power supplier. These can be prevented by adapting the processes or by turning off the respective loads.

Implementation ■

Measuring devices with communication capability, e.g. SENTRON PACs, are installed at the business’s most important locations. The SENTRON powermanager software defines limit values. If these are exceeded, a warning notification is sent, and the respective segment of the system can be manually shut down.

Benefit ■

By reducing consumption as the power limit is exceeded, it is possible to reliably comply with the provisions of agree-ments entered into with power suppliers and to avoid additional payments. Con-tinuous consumption monitoring allows for long-term process adjustments.

Highlights

Requirement ■

Facilities such as data centers, banks, or hospitals have to protect sensitive components from critical conditions like overload or harmonics that, in extreme cases, can lead to shutdowns or fire.

Implementation ■

The measuring devices SENTRON PAC and the circuit breakers SENTRON 3WL/3VL monitor the characteristics of the electri-cal power distribution. SENTRON power-manager checks the data for limit values and processes them accordingly.

Benefit ■

Limit values of critical characteristics such as cable load on the basis of moving current averages and the individual harmonics are defined and entered into the SENTRON powermanager. At the same time, a notification concept, e.g. notification via text message, is selected. This way, critical equipment values are monitored and, if necessary, a warning is issued. Power distribution failures and the associated damages can proactively be avoided.

Highlights

Equipment failure caused by over- ■

load can be avoided

Sensitive devices are protected from ■
