Systems, apparatuses, and methods are described for DC bus management. During startup, a power device may provide power at different voltages to the DC bus to ramp up the voltage of the DC bus from a zero voltage level to an operating voltage level. For ex...

In a method, operation of an electric power system which has a power utility automation system (1981-1984, 1991-1994) is monitored. The power utility automation system (1981-1984, 1991-1994) comprises a plurality of electronic devices, such as intelligent ...

The present invention proposes the use of transparent transmission of teleprotection commands in the form of GOOSE or GSSE messages, as defined by the Generic Substation Event (GSE) class model by the standard IEC 61850, between substations combined with C...

The device (100) has a microprocessor arranged such that signals of outputs (110-130) of a control module (150-1) depend directly on signals of a set of inputs (210, 230) of the module and depend on a program of the control unit and signals of another set ...

Each time a protection and control device executes an operation command on the basis of the operation command from a remote controller, an execution time thereof is stored in both of the remote controller and the protection and control device. The remote c...
