Features: With the advancement of optical fiber communication technology and the reduction in the cost of optical fiber and other communication equipment, the development of optical fiber communication in China has been rapid. The development and popularization of power communication networks have provided sufficient channel resources for the large-scale application of phase-current differential protection. Phase-current differential protection is becoming increasingly widely used in power systems, but during its use, due to a lack of accumulated operational experience and insufficient understanding of communication by protection personnel, there is a shortage of guidance materials for channel testing. This book is a summary of the author's many years of work and is divided into 6 chapters, mainly including: transmission line current differential protection, basic knowledge of optical fiber communication, communication between optical fiber current differential protection devices, differential protection optical channel testing, performance indicators of optical fiber current differential protection devices, and on-site abnormal handling. To facilitate reader use, this book also provides common issues and explanations of abbreviations and terms related to optical fiber current differential protection communication interfaces in the appendix. This book can be used as a reference for technical personnel engaged in relay protection debugging and operation in power systems, as well as for teachers and students of relevant majors in universities and colleges.
