Challenges and Learnings During Integration of Phasor Measurement Unit Data with Supervisory Control and Data Acquisition System—An Indian Experience

To improve the quality of the steel plate, The No.2 Roll Mill of Wuyang Iron and Steel Company has adopted the hydraulic reversible 11 rolls leveler developed by Taiyuan University of Science and Technology and the Taiyuan Heavy Industry Co., Ltd. The machine uses a number of advanced technologies and new equipments. For example, this plate leveler uses the Supervisory Control and Data Acquisition system, including the main operator station, the monitoring station, engineer station, etc.It also adopts Oracle 10G database system and HP 380 Server clusters to realize the management function of technical data acquisition and analysis. It is able to complete the real-time data acquisition, data analysis, model calculation and self –learning function.

Aiming at the problem that the current measurements provided by phasor measurement unit (PMU) is difficult to introduce to traditional state estimation, a new method to solve the compatibility problems of PMU and supervisory control and data acquisition (SCADA) is presented in this paper. By the rotated-pseudo-measurement (RPM) method, current measurements are transformed into the pseudo measurements and decoupled in polar coordinates, so that they could taken into nonlinear state estimation. Then the RPM method is simulated compared with the current transformation (CT) method. According to the result, it is showed that the RPM method has many advantages compared with the CT, such as independence of other measurements, small error in propagation and more significant in improving estimation accuracy. Moreover, the RPM method has the compatibility with traditional nonlinear state estimation and the fast calculating speed, which have good prospects of practice.
