Power grid on-line decision-stabilizing control system and control method based on super real-time emulation

Abstract

The invention relates to a power grid on-line decision-stabilizing control system and a control method based on super real-time emulation. According to the power grid on-line decision-stabilizing control system, a data processing module is arranged in a dispatching center, is used for acquiring power grid state information, and transmits power grid operating data to an on-line decision-stabilizing system, the on-line decision-stabilizing system is arranged in the dispatching center and sends a stabilizing controlling decision and overall power grid information to a stabilizing controlling device, the stabilizing controlling device is locally mounted at a transformer substation or a power station, and a data conversion and communication port is connected between the on-line decision-stabilizing system and the stabilizing controlling device and inside the stabilizing controlling device, and is used for data communication between the on-line decision-stabilizing system and the stabilizing controlling device and inside the stabilizing controlling device. A power grid stabilizing decision and control are carried out in real time based on the super real-time emulation, a control decision matched with actual working conditions of a power grid is obtained, a prevention and control decision and an emergency control decision are carried out simultaneously in a system, stable control is carried out on the power grid, and the stability of the power grid is effectively improved.

Description

technical field [0001] The invention relates to the field of power system stability control, in particular to a power grid online stability decision-making control system and control method based on super real-time simulation. Background technique [0002] The power system is a complex nonlinear dynamic system, and there are various stability problems such as power angle stability, frequency stability, and voltage stability. Once the power system stability is destroyed, it will cause huge economic losses and catastrophic consequences. Power system safety and stability control is an economical and effective means to ensure the stable operation of the power system, including three parts: preventive control, emergency control and recovery control. Damage, operating parameters seriously exceed the specified range, and the further expansion of the accident caused a large-scale power outage. The emergency control of the power system mainly includes various measures such as cuttin...

Problems solved by technology

When continuous faults occur in the power system within the refresh period, this method cannot update the policy table in time

[0006] Both of the above two methods have hypothetical faults and pre-decision-making processes, and essentially cannot get rid of the theoretical limitations of strategy mismatch.
