Electric energy metering verification simulating system

Abstract

The invention relates to an electric energy metering verification simulating system which is particularly suitable for a power department to conduct training assessment on staffs and belongs to the technical field of simulating system structures. The electric energy metering verification simulating system is characterized by comprising an electric energy meter and a verifying device, wherein radio frequency modules for carrying out radio communication are respectively arranged in the electric energy meter and the verifying device; the electric energy meter has metering and display function and can transmit parameters by radio frequency; and the verifying device is used for transmitting a start signal and a command signal to the electric energy meter, receiving the return data of the electric energy meter and finishing relevant data storage, has the function of simultaneously displaying with the electric energy meter and can finish the automatic verifying control function and the assessment and competing function of the simulating system. The invention can improve the technical level of an electric energy verifying simulation training device and fully ensure accurate, reliable and uniform electric energy metering, has simple structure and low cost, and greatly improves the working efficiency of a power comsumption check metering technician.

Description

technical field [0001] The invention relates to an electric energy measurement verification simulation system, which is especially suitable for the training and examination of employees in the electric power department, and belongs to the technical field of simulation systems. Background technique [0002] With the deepening of power grid reform, fundamental changes have taken place in the way of energy trade settlement, and the power sector has paid more and more attention to energy measurement, especially for technical personnel in electricity inspection and measurement. Higher post technical requirements. Therefore, the training of electric energy meter wiring inspection is becoming more and more important. However, on the one hand, electrical training equipment is generally manual wiring, which is backward in technology and dangerous, and has tended to be eliminated; In the case of one meter per household or even multiple meters per household, in order to promote balanc...

Problems solved by technology

However, on the one hand, electrical training equipment is generally manual wiring, which is backward in technology and dangerous, and has tended to be eliminated; In the case of one meter per household or even multiple meters per household, in order to promote balanced electricity consumption, many places adopt a time-of-use billing strategy. This development trend has made copying the data of electric energy meters a huge project. Started to use data collection terminals to replace the original traditional manual meter reading mode, and realized digital data collection for the power marketing system through the system interface, which improved the work efficiency of meter reading and ensured the accuracy of meter reading data. Due to power management The strictness and specificity of the meter, the diversification of the meter types, and the incompatibility of the communication protocol also put forward higher requirements for the development of the data acquisition terminal.
