摘要
数字化变电站要求一次设备智能化、二次设备网络化,其构建的关键在于采用遵循IEC61850规约的智能电子设备。现阶段数字化变电站存在不足:电子式互感器(全光互感器)在工程应用上存在线圈配置、供能影响、运行寿命等方面的问题;数据同步采集中存在任一互感器同步丢失将导致此间隔采样数据失效,造成此间隔的相关保护装置退出的问题;老站的按间隔逐步改造中存在数字化保护和传统保护兼容的问题。提出数字化变电站的信息共享不应仅限于变电站内部,而应被整个电网所共享。讨论了工程设计中的新问题:设计院和系统集成商的分工;一次和二次设计人员的分工;系统设计性能的验证;使用GOOSE后,设计、施工、调试、维护检修管理需求变化;智能一次设备的检测、标校、计量;信息安全。
Intelligent primary equipment and networking secondary equipment are required by digital substations and the adoption of IEC61850-based IEDs is the key point. Problems existing in current digital substations are summarized：ECT / EVT applications,synchronous data sampling,traditional substation retrofitting and information sharing. Problems met in engineering design are discussed：work division between design institute and system aggregation supplier,work division between primary system design and secondary system design,validation of system design performance,project management based on GOOSE,demand change of intelligent primary equipment management and information security.
