摘要：This paper proposes a both-ends power sources equivalent model based on static equivalence for the loadability of transmission line under operation condition, which can very well reflect the effect of parallel flow on the transmission line loadability in interconnected system. And the changing of parameters of the equivalent model of transmission line reflects the non-linearity and time-varying properties of power systems. This equivalent model is inferred firstly in theory. And then a practical method is given for forecasting equivalent parameters and obtaining the loadability of key transmission line under operation. At last, the feasibility and effectiveness of the equivalent model and the method are testified by continuous power flow in a 5-machines and 9-nodes system. © 2014 ICIC International.
