Embodiment Construction

[0034] like figure 1As shown, a stable limit monitoring and checking system of the present invention includes: a stable limit device, a limit monitoring and analysis device, a relay protection processing device and a data analysis device; wherein.

[0035] The stable limit device is used for.

[0036] (1) Voltage stability control, entering conventional load control or power grid emergency control, wherein, the conventional load control, according to the calculation results of its automatic control and auxiliary decision-making, sends a load cut command to the main station in the same area; The master station performs zoning calculation and regional control according to the dispatching load cutting instructions, and then the master station directly issues batch fast control instructions to the on-site interactive terminal, and the terminal cuts off the corresponding secondary load lines. Before the end of the stable control time, the user cannot Self-closing; when the master ...

Abstract

The invention discloses a stable limit monitoring and checking system, comprising: a stable limit device, a limit monitoring and analysis device, a relay protection processing device and a data analysis device. Through real-time monitoring and control of the limit, the invention analyzes the check of the stable limit and the protection fixed value, and analyzes whether the fixed value meets the requirements of protection sensitivity and power grid stability on the basis of the limit control, and avoids the fixed value caused by only considering the large and small methods. If the sensitivity and selectivity requirements are not met, the auxiliary operation mode analyst analyzes the influence of the relay protection mode or the change of the setting value on the stability level.

Description

technical field [0001] The invention relates to the field of power stability, in particular to a stability limit monitoring and checking system. Background technique [0002] The power grid grid and relay protection devices are the basis for the security and stability of the power grid. At present, stable operation limits and relay protection settings are generally used to control the security and stability of the power grid. [0003] Due to the ever-changing actual operation modes of the power grid, operators cannot real-time and accurately grasp the adaptability of the limits and protection settings involved to the actual operation mode. Therefore, how to control the limit in the power grid system, and how to monitor and analyze the stability limit and the check of the protection setting value in real time has become a key factor to ensure the reliability of the power grid. SUMMARY OF THE INVENTION [0004] In order to solve the above-mentioned defects and deficiencies ...
