Abstract

Therefore, a fast and accurate estimation algorithm would be a significantly useful tool. In consideration of the composition of the transient signals in the power systems, a new algorithm is proposed for the estimation of the power frequency phasor. Power frequency phasors are widely used in measurement, analysis, control and protection of power systems. When disturbances occur in such systems, power frequency phasors must be estimated quickly to ensure an exact restoration to normal operation. The article presents a hybrid scheme to improve the stability of the multi machine power system. The voltage regulation and the angular stability of the power system are improved with the help of STATCOM. A new standard controller for the STATCOM with a Supplemental Bandwidth Multiple Band Controller is used to improve the power supply voltage profile and to cushion the low frequency oscillation between zones. The selection of the wide area control signals is performed using the sensitivity of the eigenvalues expressed in terms of participation factor. Based on the double matrix pencil method, a unit reference matrix of complex value exponential signals is formed. The estimation of the power frequency phasor is then transformed into a brief multiplication of matrices. Thus, QR decomposition, the calculation of the generalized eigenvalue and the secondary estimate can be avoided and no complex multiplication is introduced. Therefore, the computational efficiency of the proposed method is improved compared to previous estimation techniques. The analytical and experimental investigations show that the proposed algorithm can extract the power frequency phasors with precision, stability and rapidity under the transient of the power system
