针对电网互联和电力市场化给电网安全稳定经济运行带来的挑战,阐述了互联电网在线暂态安全分析与控制的重要性,强调其在线预决策系统(OPS)不仅要考虑功角稳定性,而且要计及电压和频率的安全性,而预防控制和紧急控制也应该在协调的框架下研究。探讨了一体化OPS与调度中心其他系统的联系,以及多个能量管理系统(EMS)和多个安全稳定控制系统的数据共享;提出了相应的框架,并采用分布式并行计算技术来提高该系统的快速性和可靠性。最后介绍了一个应用实例及其实施中的关键问题。
In view of the challenges brought by grid interconnection and electricity marketization to the safe and stable economic operation of power grid, the importance of on-line transient transient safety analysis and control of interconnected power grids is expounded. OPS emphasizes not only the stability of power angle, But also take into account the safety of voltage and frequency, and preventive control and emergency control should also be studied in a coordinated framework. Discusses the connection between integrated OPS and other systems in dispatch center and data sharing among multiple energy management systems (EMSs) and multiple security and stability control systems; puts forward the corresponding framework and uses distributed parallel computing technology to improve the system Fast and reliable. Finally, an application example and its implementation of the key issues.
