Abstract

State estimate is to use the redundancy of the real-time measurement system to improve data accuracy, automatically exclude the error message caused by random interference, and estimate or forecast the system state. It is also one of the core functions of the energy management systems. During the implementation of the energy management systems in the offshore oilfields power grid, we found that the number of measurements is not enough. The measurement is inaccurate and also there is too much current measurement in the protective relaying equipment. So this chapter introduces the node injection current as state vector, meanwhile simplifies the measurement equation of the system and enables the constraints linearization, which improves the convergence speed of the program. At the same time, the current in the protective relaying equipment is introduced into the measurements to ensure the system observability. At last, the examples demonstrate this program is also reliable while the system is in the split run.
