A smart substation information integration platform structure

Abstract

The invention provides an intelligent transformer station information integrated platform structure, and belongs to the technical field of electric power system information. The platform structure comprises a I-area data server, a II-area comprehensive application server, a forward isolation device, a III-area data modeling and data processing device and a main station server. The platform structure is characterized by further comprising an SDCD-2000 transformer station data acquisition terminal acting as a point-to-point data receiving device for the forward isolation device. The forward isolation device is interconnected with the II-area comprehensive data application server and the III-area SDCD-2000 transformer station data acquisition terminal so that a data transmission channel with penetration of the isolation device is formed. Basic data are aggregated at the SDCD-2000 transformer station data acquisition terminal, and data primary processing is performed via data identification, data classification, data modeling and other modes. Besides, a DBLink data channel with a main station end is established, and the data are uploaded to a main station database in a timing way. The data of each transformer station are acquired in a unified way by the SDCD-2000 terminal and uploaded to the main station so that redundant access is effectively reduced, and access pressure of the transformer station data server is alleviated.

Description

technical field [0001] The invention belongs to the field of power system information technology, and can be applied to the information integration platform of intelligent substations [0002] framework construction. Background technique [0003] In the six links of power generation, power transmission, power transformation, power distribution, power consumption and dispatching of the smart grid, the core of the power transformation part is the construction of smart substations. As an important node of smart grid, smart substation is the continuation and development of digital substation [1] . The main features of smart substations are "intelligent primary equipment, digitalization of station-wide information, standardized information sharing, and interactive advanced applications." On this basis, in 2009, the State Grid Corporation of China released the "Technical Guidelines for Smart Substations". Data exchange between the station and the master station, etc. With the...

But at present, the descriptions of the transformation framework and standard data interface in the two documents are not perfect, and there are no a priori successful case reports at home and abroad. In view of this situation, this plan proposes the relationship between the substation and other functional departments. Standardized data transmission and access framework, and carried out a relatively systematic design and development
