Problems solved by technology

[0004]Due to the massive operation and maintenance of the low-voltage centralized reading operation and maintenance system, a large number of on-site operation and maintenance personnel are required. Due to the technical level, personnel cannot discover and solve such problems in time
However, most of the current training for low-voltage centralized copy operation and maintenance adopts the local deployment mode. The teachers in the training class simply use PPT to introduce various equipment used on site and various phenomena when field equipment fails. Usually, they can only satisfy simple, A small number of abnormal simulations, but it cannot cope with complex and multiple abnormal simulation training, and the simulation degree for some abnormalities is not high, which affects the training effect

Description

technical field [0001] Embodiments of the present invention relate to the technical field of electric energy metering, acquisition, operation and maintenance, and in particular to a low-voltage centralized reading operation and maintenance simulation system. Background technique [0002] At present, with the deepening of my country's urban and rural power grid renovation projects, the traditional electricity policy is changing to a new scientific electricity policy, and the conventional electricity price is changing to a time-of-use electricity price. Ordinary mechanical watches, electronic pulse Meters, card-type prepaid meters, etc. are gradually changing to multi-functional and time-sharing metering. Therefore, power users and power marketing departments have gradually increased the requirements for the quality, accuracy, function, degree of automation and reliability of power meters. Advocate time-sharing electricity use, use the price difference between peak and trough pe...
