SIMATIC PCS 7 powerrate Siemens (Сименс) доставка по России со склада и под заказ

SIMATIC PCS 7 powerrate is an add-on to PCS 7 which throws light on power consumption from the infeed to the load. Power data are continuously collected, archived and processed further. With an exact knowledge of the consumption profile it is possible to identify savings potential, optimize your power supply conditions and hence lower your power costs. Monitoring the contractually agreed power limit helps on the one hand to prevent unnecessarily high power prices or penalities and on the other hand to make full use of the fixed power limit.

Full integration in PCS 7 enables the easy use of standard interfaces, e.g. to SIMATIC IT, or standard functionalities from PCS 7.

SIMATIC PCS 7 powerrate is made up of the following components:

Modules for the acquisition and processing of power data
Faceplates for the presentation and processing of power data
Excel macro for allocating power data to cost centers
Components for implementing load management (calculating trends, monitoring limits, enabling/disabling loads)
Faceplates for presenting results and for configuring load management
Excel macro for determining the duration curve as a basis for load management decisions

Область применения

SIMATIC PCS 7 powerrate is used in all areas in which PCS 7 is used and energy saving considerations play a major role. Full integration in PCS 7 means that there is no need for a special system environment. Predefined modules and symbols give you the assurance of building on tested product components, with interfaces which enable customized expandability.

Особенности

Identification of power-intensive consumer devices and processes in order to introduce measures for improving power efficiency
Comparison of consumption profiles for greater efficiency of process design
Optimizing the company according to energy parameters based on an assessment of consumption and costs
Complying with the contractually agreed power limit, thus preventing higher power supply costs or penalty payments

Функции

Power data acquisition and processing

Using prefabricated modules, power data can be collected from any Profibus-capable devices. The data can exist on the modules in the form of counting pulses, count values, power values or power averages. From these data the module calculates the power averages and the work values for a predefined period. Count values can also be entered manually. These data are archived in the PCS 7 day logging archive. In addition, a limit forecast is extrapolated for each period.

A sample function (heat calculation), which can be adapted through open interfaces at any time to the needs of the process, was implemented in order to visualize customized calculations.

The data from manually read counters can be entered directly into the system and be used for further evaluations.

Presentation of the power data

The currently collected power data are presented as power averages / work values per time interval. A reserve curve presentation enables the evaluation of archived power data and their presentation in table form.

Further processing of data

The archived data can be exported directly from PCS 7 to Excel. Using predefined macros it is possible to create various reports:

Cost center report

Here the consumption can be allocated to different cost centers and the costs calculated on the basis of predefined rates. The results can be output in 2 reports in table form or as a bar graph.

Report in table form

Report as a bar graph

Duration curve

An analysis is carried out on the basis of the archived power averages to establish how often a certain power average has occurred in a given period. From this characteristic curve it is quickly evident whether there are any short-time power peaks.

Customized further processing of the exported power data is possible in addition.

If the data are archived in the PCS 7 day logging archive, they can also be accessed with PCS 7 tools.

Additional functions

To prevent the loss of data in the event of a communication fault, the data are temporarily stored in a cyclic buffer on the SIMATIC S7.

To ensure synchronicity with the power supply company, it is possible to evaluate the synchronization pulse from the power supply company.

Load management

Contractually agreed power limits (for current it is typically the 15-minute power average) must be complied with; if not, there is a threat of far higher purchase prices or even penalty payments. The load management feature of SIMATIC PCS 7 carries out cyclic trend calculations in order to issue warnings/alarm indications if violation of the limit is likely and to switch off loads in accordance with the given configuration should this be required. To prevent unnecessary switching operations there are many different parameters for adapting the load management to the current process conditions. All of which is done in simple and user-friendly manner through the faceplate.

For loads which are spread among different PLCs, SIMATIC PCS 7 powerrate has suitable AS-AS communication modules so that they too can be integrated in the load management.
