摘　　要：解列控制是电力系统安全稳定控制的最后一道防线,其作用在于阻断严重扰动在电网中的恶性蔓延,如异步机群振荡失稳,并为解开后的孤网创造一个自平衡的运行环境。成功的解列能够挽救大量的电力负荷,避免发生如2003年美加大停电、2009年巴西大停电和2012年印度大停电等类似的大范围事故,减轻国民经济损失,维持社会稳定安全;而不成功的解列则会导致系统遭受更大的冲击。该文从工程应用和理论研究两个层面对电网解列现状进行了综述,总结出当前解列控制及其理论研究中尚存的问题,包括解列面界定方法、解列时机判断等问题,并针对这些问题提出相应建议。Grid islanding is the last defense of the security and stability of power grid. It can inhibit the spreading of serious disturbance in power system, such as oscillatory and instability between asynchronous generator groups, and create self-balancing environment for every isolated island. The successful grid islanding control can save many power loads, and avoid large-scale blackout, such as the blackout of USA and Canada in 2003, the Brazil blackout in 2009 and the India blackout in 2012. So the grid islanding control would contribute to reduce the losses of national economy, and maintain the social stability and safety. On the contrary, an unsuccessful grid islanding control would suffer the power system and the society. In the paper, the development oi~ the grid islanding control had been overviewed from the aspects of engineering application and theoretical research. The theoretical research of grid islanding control and its problems were summarized, including the splitting surface definition methods and splitting timing judgment methods. Suggestions for these issues were proposed in the paper.
