Simple method and system for structuring and filing real-time running way of power grid

Abstract

The invention discloses a simple method for structuring and filing a real-time running way of a power grid. The simple method comprises a first step of structuring a data template of the power grid based on a latest structure and latest parameters of the power grid, a second step of structuring a data interface communicating with an EMS (Enhanced Message Service) according to CIM / SVG (Common Information Model) / (Scalable Vector Graphics) so as to extract real-time data from the EMS, a third step of developing a real-time running way generation module, a fourth step of structuring an exact real-time database of the power grid, and a fifth step of building connection with BPA (Bonneville Power Administration) server through a BPA interface and establishing contact between an offline BPA and an online EMS to enable the BPA to share the real-time data of the EMS. The system developed by the method can exceed the EMS on the aspect of some functions, and is an expansion and extension of the EMS function. The system established based on the method can be shared by scheduling, planning, biotechnology, design and other relevant departments or professions, and can play greater benefits within a wider range.

Description

technical field [0001] The invention relates to a simplified method for constructing and archiving the real-time operation mode of the power grid for power grid dispatching. The invention also relates to a system dedicated to said method for constructing and archiving the real-time operation mode of the power grid. Background technique [0002] The security of the modern power grid not only depends on the grasp of real-time dispatch, but also depends on the analysis of the operation mode in advance. The operation mode needs to pay attention to the present, past and future of the power grid. This work characteristic determines that the existing dispatch automation EMS cannot meet its multi-faceted work requirements, and the support of offline software is also needed. The coexistence of two software systems, online analysis and offline calculation of the power grid, is a common reality faced by the current domestic power grid operation mode, and BPA is one of the offline soft...

Problems solved by technology

[0003] Although EMS / SCADA can provide a comprehensive real-time operating condition of the power grid, it can only provide a limited type and a limited amount of historical data of the power grid for post-event analysis. Relying on the historical data provided by EMS / SCADA cannot reproduce the network topology. The historical mode of the power grid, so it is impossible to carry out substantive simulation calculations on the historical mode. At present, this kind of simulation calculation needs to be realized by using offline software

[0004] Secondly, the real-time database and picture library relied on by the advanced application software of EMS are too large to adapt to the flexible requirements of the operation mode, evaluation of power grid planning and forecasting of power load. At present, such analysis and calculation still rely on offline software.

[0005] Third, in addition to power flow calculation and static safety analysis, the operation mode also needs to achieve new work goals such as reactive power and voltage management, power grid operation risk assessment, and risk control. These new functions are difficult for EMS to support

[0006] In short, the online analysis and offline calculation co-existing work strategy implemented by the domestic power grid operation mode department to meet the work needs has resulted in overlapping resource allocation, increased database maintenance workload, and difficulties in new function development, which urgently need to be resolved
