The meter reading concentrator is installed in the management center. The concentrator is connected to the computer of the control center, and a modem can also be connected to the computer of the remote control center through the telephone network. The concentrator is connected to the meter reading collector through the bus, and reads the meter data of the user according to the instructions of the control center, and sends the data back to the control center or communicates the instructions of the main control station to the meter reading controller.
In the automatic meter reading system, the main station regularly or instantaneously records the meter reading data of the concentrator at the plant station, and the concentrator is responsible for completing the high-precision collection of the energy meter data at the plant station. The data collected by the concentrator at the plant and station includes electrical energy information: such as the current meter bottom, meter bottom or power recorded according to the survey cycle selected by the user, peak and valley level power at the end of the month, cumulative total power and maximum demand, etc .; The non-electric energy data collected at the plant site includes current, voltage, active power, four-quadrant reactive power, PT phase loss, CT disconnection, power loss and voltage loss. The data and electricity amount of the energy meter copied by the system can be used as the basis for electricity bill settlement. It can be directly used to calculate electricity bills, calculate the balance of bus electricity balance and line loss analysis, and can be used for load forecasting in the electricity market. Event information, can provide reliable power supply statistics (power failure record) and voltage qualification rate monitoring function. In the case that the power supply bureau's automation system meets the requirements, the concentrator can also receive the switch gate signal of the automation system to automatically replace the bypass. The centralized meter reading management system can be used with geographic information systems (professional graphic GIS) and marketing management information. The system, MIS and load control system are networked to further improve the overall management level of power supply marketing and operation.
