T/CES 022-2018 Unified Power Flow Controller (UPFC) Engineering Secondary Equipment Handover Test Specification

Scope

Scope: This standard specifies the test requirements, projects, conditions, and contents for the test phase of individual and subsystems of secondary equipment for unified power flow controllers (UPFC) projects. This standard applies to newly installed electrical secondary equipment for 220kV and 500kV UPFC projects. Other voltage-level UPFC projects may refer to this standard for implementation. Main technical content: With the completion and commissioning of China's first UPFC project and the world's first UPFC project based on modular multilevel converter (MMC) technology—the 220kV Nanjing West Ring Network UPFC Demonstration Project—and the subsequent commissioning of the Shanghai 220kV Yunzao Bay Substation UPFC Project and the Suzhou 500kV Mudu Substation UPFC Demonstration Project, the application of UPFC technology will continue to expand nationwide to address the challenges of flexible power flow control in power grids. Conducting acceptance tests for secondary equipment in UPFC projects to comprehensively evaluate the functions and performance of individual and subsystems of UPFC projects is crucial for the smooth progress of system testing and ensuring the reliable operation of the projects. Currently, there are no standards for acceptance tests for secondary equipment in UPFC projects at home or abroad, and there is an urgent need for corresponding standards to standardize the items and methods of on-site acceptance tests for UPFC secondary equipment, improve the completeness and accuracy of the tests, and provide effective reference for equipment manufacturing, design, operation, and maintenance. The development of this standard can further guide the projects and requirements for acceptance tests for secondary equipment in UPFC projects and provide an effective reference for the implementation of acceptance tests for secondary equipment in UPFC projects, enhancing the level of equipment operation and management. This standard focuses on the new demands
