Abstract

The invention discloses a line parameter correction method based on parameter sensitivity, which is used for the correction of line parameters of a power system. The power system comprises a generator, a load, a transformer and a line. The method comprises the following steps: obtaining the original parameters of the power system and marking the suspicious lines through calculation; Judging the measured data on the suspicious line and marking it as the line to be corrected if there is no data error; calculating the correction amount and correcting the line to be corrected. The method comparesthe calculation result of the system power flow with the measured value, can accurately and quickly find out the line needing to revise the system parameters, and has universal applicability.

Description

technical field [0001] The invention relates to the technical field of power system control, in particular to a line parameter correction method based on parameter sensitivity. Background technique [0002] Basic power system analysis calculations such as state estimation and power flow calculation are based on the correct parameters of the given network components. Correct component parameter values ​​are very important to the dispatch center. It is not only the basis for state estimation, but also an essential prerequisite for realizing the automation of the power grid. With the development of substation automation and communication technology, the accuracy and coverage of telemetry and remote signaling of dispatching automation system have been greatly improved. However, in actual engineering, due to inaccurate data provided by manufacturers and inaccurate grasp of information such as line reconstruction and operating environment changes, parameter errors have increasing...
