Description

Technical Field

[0001] The present invention belongs to the technical field of electric power dispatching, and in particular relates to an electric power dispatching evaluation method and system. Background Art

[0002] Power dispatching is an effective management method to ensure the safe and stable operation of the power grid, reliable external power supply, and orderly progress of various power production work. The specific work content of power dispatching is to judge the safety and economic operation status of the power grid based on the data information fed back by various information collection equipment or the information provided by the monitoring personnel, combined with the actual operation parameters of the power grid, such as voltage, current, frequency, load, etc., and comprehensively consider the development of various production work. Operation instructions are issued through telephone or automatic system to command on-site operators or automatic control systems to make adjustments, such as adjusting the output of generators, adjusting load distribution, switching capacitors and reactors, etc., so as to ensure the continuous safe and stable operation of the power grid. In recent years, with the continuous development of science and technology, modern monitoring and control methods have been continuously improved, and the technical support for power dispatching has become increasingly powerful.

[0003] To execute power dispatch, the existing technical solution with patent application number "CN201820394956.8" and patent name "An information-based distribution network dispatching and control device" is often used to execute power dispatch, which includes a power collector, voltage sensor, current sensor and display screen connected to the central controller. The power collector, voltage sensor and current sensor are used to collect the power value, voltage value and current value of the distribution network cable respectively and transmit them to the central controller. The central controller is used to transmit the collected power value, voltage value and current value of the distribution network cable to the display screen for display. The display screen is used to transmit dispatch instructions to the central controller based on the power value, voltage value or current value of the distribution network cable (the dispatch instruction can be a message indicating whether the power value, voltage value or current value of the distribution network cable exceeds the set critical value), which is convenient for staff dispatch and control. The dispatch instruction and the power value, voltage value or current value of the distribution network cable are the distribution network dispatching values.

[0004] The transmission of distribution network scheduling values ​​between the central controller and the display screen is affected by the distribution network scheduling value coordination rules. During the transmission of distribution network scheduling values ​​of some non-real-time coordination rules, there is a lack of evaluation of the coordination of distribution network scheduling values, which makes it impossible to guarantee the accuracy of the transmission of distribution network scheduling values ​​between the central controller and the display screen. Summary of the invention

The present invention evaluates the coordination of the dispatching values ​​between the central controller and the display screen at the current time point, which is suitable for ensuring the accuracy of the transmission of the distribution network dispatching values ​​between the central controller and the display screen, and ensuring that accurate distribution network dispatching values ​​can be obtained.
