Universal Automated Control Systems

Technology Automated System of Energy Resources Control

At the moment, many modern electrical appliances are made on the basis of electronic computing components, regardless of their purpose. Having its own microprocessor and memory, such a device is a microcomputer capable of processing the storage and transmission of any information. A typical example is a modern electronic meter or a complex of equipment based on System of Energy Resources Control (ASERC), such as: water, heat and gas.

Virtually every such device is equipped with a digital data transmission interface (in some cases several at once) as wired: RS485, RS232, CAN, Ethernet, PLC, 1Wire, etc. and wireless: LoRa, ZigBee, NB IoT, Wi-Fi, GSM, Bluetooth and so on.

Automated System of Energy Resources Control for household consumers (ASERC): is a hardware-software complex consisting of electronic energy metering devices integrated on the object into a single network through one of The above technologies. Also included is software that allows you to manage this complex through a user device, such as a personal computer, smartphone, tablet, etc.

AMR for household consumers:

It is not a secret to anyone that in garden and country partnerships, cottage villages, garage cooperatives and many apartment buildings located in the Russian Federation, there are problems with taking into account and paying for consumed energy resources such as: electricity, water, gas and heating. The main problem lies in the fact that the funds collected from subscribers for energy are not enough to pay the bills issued by sales companies. The difference between the invoice amount from the sales company and the money collected from subscribers can go up to 50% or more. This difference has to be compensated from common funds in order to avoid shutting down for non-payment by a supplying company that has this capability.

The reasons for the shortage of funds can occur for the following reasons:

The presence of technical losses in electrical networks:
Losses in transformer, wires and contact connections. These losses cannot be completely eliminated; they can only be reduced by carrying out certain technical measures. The value of technical losses is usually 2-11% of the total consumption, if the electrical networks are made in compliance with the existing rules and are in a satisfactory condition.
Poor condition of existing metering devices:
If metering devices have not passed metrological verification for a long time, the undercount can be a significant amount. All metering devices should be periodically checked by authorized organizations, only in this case, the reliability of the readings is guaranteed. Electronic metering devices usually have significantly longer time intervals between calibrations than electromechanical ones and can reach 16 years depending on their type.
Energy consumption bypassing metering devices (energy theft):
This component often reaches 40% of total consumption. If the metering device is installed in the house, then it is easy to organize consumption around the meter, and it is not always easy to identify it. Thus, for those who steal energy resources, the conscientious consumer partly pays.

Technical losses can not be eliminated, and you can only reduce the amount of losses. Other reasons can be eliminated by transferring metering devices from houses to a place where access to them will be almost impossible. In the case of electricity meters, it is optimal to install on poles in the immediate vicinity of live wires. It is also beneficial in terms of consumables and electrical work performed. If existing metering devices (installed at the subscriber) meet the technical requirements of the system (almost any multi-tariff meter), then there is no need to change them, and you only need to connect to the system ASERC that also saves money.

Functions of the standard system of automated metering system:

  • Automatic collection of electricity consumption (supply) metering data for each metering point (group) at specified intervals.
  • Storing accounting parameters in a database.
  • Providing multi-tariff metering of electricity consumption (supply).
  • Ensuring control over compliance with energy consumption limits.
  • Output of calculated parameters to the terminal and / or to the printing device at the request of the operator.
  • Maintain a single system time with the possibility of its adjustment.
