Abstract
As telemetering and SCADA applications are increasingly being employed by the National Grid dispatch center, it would be productive to assess the integrity of the data flow from remote measuring points. It is inevitable that errors would creep in due to a variety of factors ranging from flawed meters to a noisy communication channel. The objective of this project is to setup a state estimator to correlate the mw flow readings using DC flow methods in conjunction with a weighted -least-square estimator. The work is done inclusively on computer simulation using MATLAB language and LOAD FLOW program. It consists of four stages: - 1st stage: the mw flow in National Grid (NG) transmission lines. 2nd stage: the mw flow after a shift in generation output. 3rd stage: the mw flow after an outage of line. 4th stage: the mw flow state estimator for the three stages above.
