FORMATION OF ORTHOGONAL COMPONENTS OF INPUT SIGNALS IN DIGITAL MEASURING PROTECTION ELEMENTS WITH CORRECTION OF DYNAMIC ERRORS

Formation of Orthogonal Components of Input Signals in Digital Measuring Protection Elements with Correction of Dynamic Errors

Digital measuring elements in microprocessor protections of electrical installations are implemented mainly with the use of orthogonal components of input signals.To form orthogonal components in microprocessor protections, digital Fourier filters are most widely used, the action of which is al-ways inertial in transient modes.As a result, a dynami
