Abstract
The invention provides a load control and multi-channel time-sharing charging electric energy composite management system, including a main control module, a data acquisition module, a time module, a meter reading module, an execution module, a display module, a communication module, a keyboard control module, and a power supply module , the data acquisition module, time module, meter reading module, execution module, display module, communication module, keyboard control module are connected with the main control module and the power supply module, and the meter reading module is connected with each electric meter in the grid. A method implemented by using the above system, through the calculation and analysis of the data obtained by the signal acquisition module of the system, the power measurement and control are performed; combined with the meter reading module and the time module, it manages multiple electricity bills that do not have the time-sharing charging function. It has the functions of multi-rate meter communication, time-of-use billing, demand statistics, load shedding, etc. The invention has the characteristics of simple operation, convenient use, favorable transformation, cost saving and good economic benefit.
Description
technical field [0001] The invention relates to electric power quantity measurement and electric energy management technology in the electric power industry, in particular to a load control and multi-channel time-sharing billing electric energy compound management system and its realization method. Background technique [0002] In recent years, with the continuous emergence of new technologies, the product structure of electric energy meters has undergone tremendous changes. At present, there are hundreds of types of electric energy meters, the annual production capacity is about 200 million units, and the market capacity is about 80 million to 90 million units. Since the first electric energy meter was developed by our country, electric energy meter products have undergone several updates, especially in recent years, in order to keep pace with the development of international electric energy meter products, no matter in terms of technical level, production level, or product...
