状态估计已成为现代控制中心的重要工具。如果能够提高状态估计的精度，这将意味着可以获得更可靠的电力系统表示，运行和控制功能可以做出更好的决策。研究了输电线路电阻随温度变化对状态估计性能的影响。用直线热平衡方程和气象资料说明了在状态估计中考虑这种影响的可能性。
State estimation has become a tool of vital importance in modern control centers. If the accuracy of the state estimation could be increased this will mean that a more reliable representation of the power system is obtained and the operation and control functions can make better decisions. This paper studies the influence of changes of the transmission lines resistance due to temperature on state estimation performance. The possibility to account for this effect in state estimation is shown by the use of Line Heat Balance equation and weather data.
