摘　　要：联络线功率偏差是互联电网控制运行的重要指标之一,T1和T2标准对联络线功率偏差的控制效果进行考核与责任分配,其合理性将对联络线功率控制的有效性产生重要影响。当前的T2标准简单沿用了CPS2标准,并不适合对联络线功率偏差进行考核。因此从互联电网的联络线功率控制目标出发,以CPS(control performance standard)标准的理论为框架,采用与CPS标准一致的若干假设,推导了互联电网的T2考核标准,其本质是一套ACE(area control error)考核带宽。其次,将提出的T2标准与CPS2标准进行了对比,对比了不同控制目标对控制区的要求。最后通过实际电网数据的算例分析,表明了采用所提出的T2标准,比直接沿用CPS2标准作为T2标准具有更好的考核效果,从而验证了其有效性。Tie-line power error is an important index for operation and control in an interconnection. T1 and T2 criteria are used for evaluation and responsibility-distribution of control performance of tie-line power error. Reasonability of the criteria exerts strong influence on effectiveness of tie-line power control. However, existing T2 criteria simply uses CPS2 criteria, possibly not suitable for tie line power error evaluation. According to control target of tie line power error, based on theoretical framework and several assumptions of control performance standard （CPS）, this paper deduced a new T2 criteria. Essence of T2 criteria is a set of ACE （area control error） boundaries. Comparison between the proposed T2 criteria and CPS2 criteria was presented, showing difference between requests toward different control targets. Simulation results based on actual data showed that the proposed T2 criteria can bring a better evaluation effects than CPS2 as T2, thus verifying effectiveness of the proposed T2 criteria.
