Energo-Holding: ASCAPC large consumers

A system is intended for electricity metering of large consumers: industrial enterprises, office centers and also transformer substations.

A system works with the metering devices of all Russian producers equipped with digital (CAN, RS 485, RS 232) interfaces.

TP with a large number of points of accounting is controlled by one device.

Galvanic untied digital interfaces allow to do a system taking into account on the low and high party.

Performs collecting and processing of indications from metering devices and transfer of the consolidated information on GSM/GPRS network from 64 counters on one object.

Conforms to all requirements of application 11.1 of NP ATS:

• Collecting and Processing of results of measurements;
• Access to collected information from IVK;
• Time synchronization of counters;
• Self-diagnostics;
• Maintaining event log;
• Storage of daily data on 30-minute increments on each channel of 35 days;
• Power consumption per day on each channel not less than 35 days;
• Power consumption in a month on each channel not less than 12 months.

Gives an opportunity of providing an alternative channel.

Performs self-diagnostics and does not require maintenance.

Competitive advantages of GSM/GPRS

• Significant reduction in cost of traffic at any regulations of poll.
• Repeated increase in capacity of a communication channel.
• Time of poll does not depend on the number of attached devices, and is defined by the capacity of the server of data collection.
• Possibility of remote removal from counters of all data array, when preserving speed of poll.
• Buffering of data is provided and the server of data collection is capable to store tens of thousands of accepted messages while the SMS center up to 100 SMS on one SIM card.
• Significantly big resistance of a system to transmission errors.
• For the USPD to which 100 metering devices are connected (values of active energy are transferred).
