Abstract

The invention discloses a grid scheduling control system comprising a data analysis and processing center, a communication module, a monitoring module and a scheduling module. The communication module is communicatively connected with an information acquisition module. The information acquisition module includes a current transformer, a voltage transformer and an acquisition terminal. The communication module is also communicatively connected with a power control module and a smart terminal. The power control module comprises a relay controller communicatively connected with the communication module. The relay controller is connected with a relay connected in series with a standby power supply. The grid scheduling control system utilizes the controllable load amount of a user to shut down the low-priority household appliances of the user by using the smart terminal to reduce the total load amount of the user, thereby reducing the maximum power load of the power grid at the peak hours of power consumption, reducing the cost of equipment such as transformers and power lines in the construction of the power grid and the replacement and maintenance cost of the transformers, and improving energy efficiency.

Description

technical field [0001] The invention relates to the field of power grid control systems, in particular to a power grid dispatching control system. Background technique [0002] In reality, the use of household appliances is increasing, and the demand for electric energy is also increasing, especially during the peak period of electricity consumption. Balanced to ensure the power demand during peak hours, often use the highest power load to set up the power grid. However, the problem that exists in this way is that the power grid is erected according to the highest power load, and the requirements for transformers, transmission lines, control and detection equipment of each node are very high, the total cost of construction is high, and the cost of transformer replacement and maintenance is also high very high. In non-peak hours, some power generation capacity is idle, and the energy utilization rate is not high. In recent years, with the aggravation of problems such as en...
