Abstract

The invention discloses a dynamic capacity-increasing and effect-raising method for sharing local grid multi-system fused big data. Collection and transmission of transformer information are realized through communication established with a scheduling integrated management system D5000 and a production management system PMS; weather information needed for electric transmission and transformation equipment load prediction is acquired through pushing for an electric power weather information system; real-time and dynamic information supporting is provided for optimization of operation mode in combination with load prediction information of a local grid load dynamic management system by adopting a system heat stability threshold and a tide distribution value provided by electric power system computation system PSASP, and the implantation for a multi-system communication cut-through fusion and big data information interaction sharing technology provides effective technical management means for realizing electric transmission and transformation equipment dynamic capacity increase, fully developing equipment hot redundancy and promoting system integration load capacity for local grid dynamic load intelligent dispatching management.

Description

Technical field: [0001] The invention relates to the field of power transmission and transformation, in particular to a method for dynamically increasing capacity and improving efficiency through multi-system fusion and big data sharing of a local power grid. Background technique: [0002] With the continuous and rapid growth of social economy, the electricity load is increasing rapidly. At present, the load dispatching of the power system is generally based on the thermal stability limit of the equipment and the dynamic stability limit of the system to determine the dispatching mode of the power flow. The thermal stability limit of the equipment currently given is a static value, such as considering the worst weather environment of the year (such as ambient temperature 35-40°C, wind speed 0.0m / s, sunshine intensity 1000W / m2), 500kV The line has 4x400 conductors, and the maximum current carrying capacity is 2400A. The dispatching department arranges the transmission capacit...
