Problems solved by technology

[0003] For section stability limit management, the current stable section monitoring in production and operation is based on the "offline calculation, online monitoring" mode to realize online monitoring and over-limit alarm of section stability limit; but in actual operation, on the one hand, the section stability limit is identified and monitored online The important factors affecting the stability limit (such as the switching on and off of the stability control system, etc.) have not been fully considered, and cannot accurately reflect the section stability limit of the actual power grid; on the other hand, there is no means for online verification of the section stability limit formulated offline

Embodiment Construction

[0027] Below in conjunction with accompanying drawing, the present invention will be further described:

[0028] Liaoning Provincial Electric Power Co., Ltd. and NARI Group Corporation conducted a long-term research and design work on the development of intelligent transmission section limit management and online dynamic checking system, and finally decided to jointly build an intelligent The overall scheme of the transmission section limit management and online dynamic checking system to realize the centralized monitoring and management of the Liaoning power grid section limit, and to realize the calculation of the feasible range of the section limit power.

[0029] The present invention aims to improve the practical level of section stability limit management, and plans to implement it in two steps: the first step is to complete the limit management and online monitoring technology; the second step is to study the automatic calculation technology of the stable section limit f...

Abstract

The invention relates to a power system intelligent transmission interface management and online security checking system, which includes a transmission interface limit management module, a transmission interface limit online monitoring and alarm module, and a transmission interface extreme power feasible interval calculating module. The transmission interface extreme power feasible interval calculation is achieved on the basis of transmission interface limit online monitoring, the automation degree of the limit monitoring is increased, and an auxiliary support is provided for users in various posts for stable transmission interface extreme management.

Description

technical field [0001] The invention belongs to the field of smart grid dispatching, and mainly relates to an intelligent power system section management and online safety checking system. Background technique [0002] As an important energy base in Northeast my country, Liaoning Power Grid has formed a long-distance, large-scale AC-DC hybrid sending-end power grid. On the one hand, it needs to gather power from large energy bases to ensure external transmission capacity; on the other hand, it needs to supply power to local loads to support the safety of the local power grid. Stable and reliable operation, so higher requirements are put forward for power grid operation analysis and control decision-making. In particular, the interactive influence of the transmission capacity of large-scale hydropower transmission series and parallel channels is crucial to the safe and stable operation of the power grid. [0003] For section stability limit management, the current stable sect...
