Scope
Scope: This standard specifies the conditions of use, basic technical parameters, technical performance requirements, structural and component requirements, and testing requirements for oil-immersed series transformers used in unified power flow controllers (UPFCs). This standard applies to 500kV and 220kV oil-immersed series transformers used in unified power flow controllers. Other voltage levels may be referenced for implementation, hereinafter referred to as series transformers. Main technical content: Unified power flow controllers are thyristor-controlled devices that can independently or simultaneously perform various functions such as parallel compensation, series compensation, phase shifting, and terminal voltage regulation. They can adjust power flow and enhance the transmission capacity of the system without altering the grid structure. By rapidly absorbing reactive power and dynamically supporting the voltage at the connection point, they improve system voltage stability and represent an advanced flexible transmission technology. Currently, China is planning and constructing multiple unified power flow controller projects, where series transformers differ significantly from conventional power transformers in terms of structure, technical parameters, and testing. Existing transformer standards cannot regulate this new type of transformer. The preparation of this standard aims to regulate the conditions of use, basic technical parameters, technical performance requirements, structural requirements, and testing of this new type of transformer, providing reference and standards for subsequent similar projects. This standard is based on the Nanjing West Ring Network 220kV unified power flow controller project and the Suzhou 500kV UPFC project, and regulates and references the conditions of use, basic technical parameters, technical performance requirements, structural requirements, and testing of 220kV and 500kV series transformers.
