Abstract

The embodiment of the invention discloses a power grid measurement data and power grid model correction method. The method comprises the following steps: acquiring power grid measurement data and power grid model data from a data acquisition and monitoring control system; performing state estimation of the actual operating state of the power grid according to the power grid measurement data and the power grid model data; matching the result of the state estimation with the preset conditions, and positioning the error in the power grid measurement data and the power grid model data according to the matching conditions; and correcting the positioned error according to the preset rule. The invention also discloses a power grid measurement data and power grid model correction device. According to the method, the accuracy of the power grid measurement data and the power grid model data can be improved, and a guarantee is provided for performing advanced application based on the data.

Description

technical field [0001] The present application relates to the field of power grid technology, in particular to a method for correcting errors in power grid measurement data and a CIM model and a corresponding device. Background technique [0002] In order to adapt to the development of electric power technology and meet the higher and higher demand for electricity under the new situation, the construction of smart grid has been carried out on a large scale. The key to smart grid lies in intelligent dispatching. The so-called intelligent dispatch refers to the active and intelligent monitoring, analysis, early warning, auxiliary decision-making and self-healing control of the power grid through state estimation, optimal power flow calculation, reactive power optimization, stability analysis and fault calculation. The basis of intelligent dispatching is to provide power grid measurement data and power grid model through the network topology, and then realize it through networ...
