Description

technical field

The invention relates to the field of electric power, in particular to a simulation training system for collecting electricity consumption information.

Background technique

In the early days, it was also called power load management system, power information collection system, and remote centralized meter reading system.

The electricity consumption information collection system is an important part of the construction of the smart grid. According to the overall requirements of the State Grid Corporation of China for the construction of the smart grid, the construction of the electricity consumption information collection system should achieve the overall goal of "full coverage, full collection, and full cost control". In 2013, the power grid company has completed the formulation and improvement of all relevant specifications for smart meters and electricity consumption information collection systems.

Full coverage means that the power consumption information collection system should cover all kinds of power users in the operating area of the power company. Full collection is to realize remote automatic collection of electricity consumption information of various metering points covered by the electricity consumption information collection system. Full cost control means that the power user information collection system can continuously collect the user's electricity consumption, calculate the amount of the remaining electricity charge and display it to the user, prompt the user to pay when the remaining electricity charge is not much, and when the remaining electricity charge is lower than the set amount Execute power purchase trip control, and the system orders the electric energy meter to close and restore power supply after the user completes the payment. To achieve the above goals, it is necessary to fully apply smart energy meters: for new users, smart energy meters with cost control functions should be used; for power supply areas or places that originally used energy meters without cost control functions, smart energy meters must be transformed. Some energy meters are replaced with smart energy meters with cost control functions.

At present, companies in various cities have invested a large amount of electric energy data collection terminal equipment, and other cities that have not invested in them will also realize various functions of the system one after another. The design and construction of the electric energy information collection system and equipment operation and maintenance are completed by electric energy metering personnel, with high technical content and heavy workload.

Due to the complexity of the on-site environment and the reliability of the collection terminal and meter operation, there is a large workload in project construction and later operation and maintenance, and it is difficult for the current system to appear in the actual engineering design, construction, operation and maintenance process. To solve some problems, there is still a lack of test analysis and training platform, lack of simulation environment for the further application, function development, and skill training of the power consumption information collection system, and lack of training, demonstration and practical training for power consumption information collection, operation, maintenance and debugging personnel place.
