新型电力系统保护控制技术架构研究OACSTPCD
A study on a technical architecture for protection and control of new-type power systems
随着新能源的不断接入,电力系统结构、运行控制方式变得更为复杂,对保护控制技术提出了更高要求.为此,提出了一种新型电力系统保护控制技术架构.为预防单一事故向系统性事故发展,提出新型继电保护构成模式,构建更加完善的第一道防线.结合系统性事故演变过程,建立保护和控制系统之间的信息融合及协同机制,通过站域自治-区域协同的方式实现自治式保护控制策略,优化三道防线的功能布局,有效抑制和阻断系统性事故的发生与发展,提升新型电力系统的安全防御能力.
With the increasing complexity of power systems due to the integration of new energy sources,there is a heightened demand for advanced protection and control technologies.In response to this challenge,a protection and control architecture designed for new-type power systems is presented.To prevent isolated incidents from cascading into system-wide failures,a new relay protection configuration model is proposed to establish a more robust guard.In view of the evolution of incidents across the system,an information integration and coordination mechanism is es-tablished between protection and control systems.Through a combination of station-level autonomy with regional col-laboration,the autonomous protection and control is fulfilled.The functional layout of the three guards is optimized to effectively suppress and disrupt the occurrence and development of incidents in the systems and thereby enhances the safety defense capabilities of the new-type power systems.
