Portable smart electric energy meter simulation system and its operation method

Abstract

The invention relates to a portable intelligent electric energy meter simulation system and an operation method. The system includes a trolley case, which includes a box with a built-in simulation system, a cavity for placing an electric energy meter is provided in the middle area of ​​the front of the box, and a cavity for placing a display is provided above the cavity. The display window of the screen, the side wall in the cavity is provided with an interface, so that the data communication interface of the electric energy meter is connected to the simulation system through the interface and the interface circuit corresponding to the interface, and the simulation system also It is connected to the display screen through a display screen driving circuit, and the emulation system is also connected to the splitter arranged under the cavity through a USB interface circuit, and the side of the splitter is provided with an accommodation slot for placing a PDA. The invention provides a portable intelligent electric energy meter simulation system capable of fully simulating the operating conditions of the on-site electric energy meter, so as to better conduct training and assessment work for relevant types of work involving the intelligent electric energy meter in the electric power system.

Description

technical field [0001] The invention relates to a portable intelligent electric energy meter simulation system and an operation method thereof. Background technique [0002] Existing data collection and assessment work can only be realized in fixed simulation devices. Some grassroots power supply companies are unable to provide simulation devices that can meet the assessment conditions due to limited conditions, and the existing devices cannot be combined with the bottom of the electric energy meter. and other internal parameters for more complex fault setting and event setting. At the same time, since the bottom of each electric energy meter is fixed and the number of the electric energy meter is fixed, the electric energy meter needs to be replaced frequently during the assessment process. A large amount of data maintenance work is not conducive to the assessment work with a large number of people. This requires the upgrading of existing equipment and the construction of ...
