A state estimation method is presented, which is based on the measurement transformation approach. In this approach, a set of power measurements is transformed into a set of adequate currents. The method is analysed in detail and some modifications, which should improve the statistical properties of the estimator, are proposed. The necessity for modifications is proved both analytically and computationally. The paper also contains results of the simulation studies made on the Polish power system, in which the modified method was compared with some other state estimation methods.
