35 kV integrated intelligent substation

Abstract

The invention provides a 35 kV integrated intelligent substation. The 35 kV integrated intelligent substation comprises an integrated information platform, an integrated substation area protection and measurement control device and a comprehensive intelligent assembly, wherein the comprehensive intelligent assembly receives sampling values and state information of a primary intelligent device, and transmits the sampling values and the state information to the integrated substation area protection and measurement control device, full-substation protection and measurement control logical judgment of the substation is carried out through the integrated substation area protection and measurement control device, and a GOOSE instruction is issued to the comprehensive intelligent assembly to achieve intelligent measurement control over the primary intelligent device; meanwhile, the integrated substation area protection and measurement control device transmits the logical judgment result to the integrated information platform, and receives scheduling instructions and control instructions of the integrated information platform. According to the 35 kV integrated intelligent substation, the construction mode of 35 kV intelligent substation is updated, the integration degree of software and hardware devices in the 35 kV integrated intelligent substation is improved, the types and the number of secondary intelligent devices are reduced, operation and maintenance difficulty is reduced, automation construction cost of the 35 kV intelligent substation is reduced, and popularization and application of the 35 kV integrated intelligent substation in the process of rural power grid construction and transformation are facilitated.

Description

technical field [0001] The invention belongs to the technical field of substation automation, and in particular relates to a 35kV integrated intelligent substation. Background technique [0002] The 35kV substation is the key link connecting the rural smart transmission network and the smart distribution network. At present, the professional equipment of the comprehensive automation system of the 35kV conventional substation is repeatedly configured, repeatedly collected, and the data source is inconsistent, and information interaction between the equipment cannot be carried out. Protection Lack of coordination, "fragmentation", equipment manufacturing does not follow unified standards and specifications, does not have interoperability and interchangeability, and cannot adapt to the requirements of smart grids. [0003] At present, the pilot projects of smart substations are mainly concentrated on the voltage level of 110 kV and above. The automation system adopts a layered ...

[0002] The 35kV substation is the key link connecting the rural smart transmission network and the smart distribution network. At present, the professional equipment of the comprehensive automation system of the 35kV conventional substation is repeatedly configured, repeatedly collected, and the data source is inconsistent, and information interaction between the equipment cannot be carried out. Protection Lack of coordination, "fragmentation", equipment manufacturing does not follow unified standards and specifications, does not have interoperability and interchangeability, and cannot adapt to the requirements of smart grids

For 35kV smart substations, there are currently no corresponding construction standards and norms. If the typical layered and decentralized construction model is directly applied, there will be problems such as increased number of smart components, low technology integration, and excessive investment in secondary equipment, which is not practical. value
