All-service unification modeling method based on time series

Abstract

The present invention discloses an all-service unification modeling method based time series. The method comprises the following steps that S1, a data structure system integrating a public power-grid model and a business model of time labels is established, and unified maintenance is performed on an all-service models/graphs according to time series so as to form a model database; S2, each business system extracts a public power-grid model and a business model of any time section from the model database as needed; S3, each business system generates a communication index table as needed, and performs collaborative verification by combining the extracted public power-grid model and the extracted business model with the generated graph of the time section; S4, after successful verificationthe on-line synchronization of the public power-grid model and the business model is performed on an on-line running system; for an off-line system, the public power-grid model and the business model are sent to each business system in a mode of a CIM/E file. The method disclosed by the present invention realizes the thorough separation of the running and the maintenance of a power-grid dispatching control system, so that the stability and the reliability of on-line systems are improved.

Description

technical field [0001] The invention relates to a unified modeling method, in particular to a time-series-based unified modeling method for regulating and controlling all services, and belongs to the field of electric power system scheduling automation. Background technique [0002] The smart grid dispatching control system has played an important role in the construction of the "big operation" system, providing good technical support for the system coordination between control centers at all levels and the integrated operation of all services within the control center. Based on the basic platform of the smart grid dispatching control system, the model splicing technology based on CIM / E is adopted to realize the source maintenance and global sharing of models and graphs between control centers at all levels. Sharing of models and graphics among users. [0003] However, some deficiencies have been found in the actual operation of the existing smart grid dispatching control s...

AI Technical Summary

Problems solved by technology

[0003] However, some deficiencies have been found in the actual operation of the existing smart grid dispatching control system, which are mainly manifested in: (1) The model of the smart grid dispatching control system mainly meets the needs of dispatching production and operation, and the models of other applications of the control center, such as The comprehensive stability analysis model, the operation mode model, etc. have not really been integrated, resulting in repeated modeling of various application systems and inconsistent information.

(2) The real-time state, planning state, and test state of the smart grid dispatching control system are logical states. When the system is maintained based on the planning state and test state, it often affects the real-time operation system, resulting in unstable system operation.

(3) The management system of model data is not perfect

The regulatory agency has not yet established a model data maintenance and management system that runs through the entire process of power grid planning and design, engineering construction, new equipment commissioning, and commissioning. It is necessary to improve the model maintenance process from the future to the present, and the coordinated operation of online and offline

(4) The pre-verification of the smart grid dispatching control system often interferes with the normal operation of the real-time system due to misoperation
