为了促进电网调度精益化和智能化发展,新一代智能调控主站不断引入新技术来应对所面临的挑战。引入电网稳态时标量测的概念,设计了时标量测在智能调控主站的应用方案,并着重阐述了集成时间序列数据库的统一支撑平台、支持时标量测的实时监控、基于时标量测的状态估计和基于时间序列数据库的开放式综合数据平台等关键技术。成果已成功应用于苏州地级和江苏省级智能电网调度技术支持系统等试点工程,满足各级调度机构智能调控主站的实际应用需求。
In order to promote the development of smart and lean dispatching, the new smart control center constantly introduces new technology to deal with the challenge. The paper systematically introduces the concept of time stamped measurements for steady state grid and then proposes a key technical scheme for application of time stamped measurements for smart control centers. Finally, some key technologies including unified application support platform integrated with time sequence database, supervisory control and data acquisition (SCADA) supported by time stamped measurements, state estimation based on time stamped measurements and open data platform based on time sequence database of the scheme are studied. The research result has been applied in pilot projects of smart grid dispatching technology support system in Suzhou City and Jiangsu Province, respectively.
