Abstract:
THE INVENTION RELATES TO A METHOD FOR REMOTELY CONTROLLING AND/OR REGULATING AT LEAST ONE SYSTEM (1), IN PARTICULAR AN INDUSTRIAL SYSTEM USING A COMMUNICATIONS DEVICE (2) WHICH IS ASSIGNED TO THE SYSTEM (1), AND AT LEAST ONE RECEIVER DEVICE (3), INFORMATION RELATING TO THE SYSTEM BEING TRANSMITTED FROM THE COMMUNICATIONS DEVICE (2) TO THE AT LEAST ONE RECEIVER DEVICE (3), THE INFORMATION CONTAINING A VALIDATION CODE WHICH IS' GENERATED BY THE COMMUNICATIONS DEVICE (2), A MESSAGE BEING RECEIVED BY THE COMMUNICATIONS DEVICE (2), THE COMMUNICATIONS DEVICE (2) EXTRACTING A CHECK CODE AND INSTRUCTION INFORMATION FROM THE MESSAGE ACCORDING TO A FIRST EXTRACTION RULE, THE COMMUNICATIONS DEVICE (2) VALIDATING THE MESSAGE BY MEANS OF THE VALIDATION CODE AND CHECK CODE, AND THE INSTRUCTION INFORMATION BEING IMPLEMENTED BY THE SYSTEM (1) ONLY WHEN THE VALIDATION IS SUCCESSFUL.
Abstract:
Programmable protection function installation method in a protection unit (1) of an electrical power network has the following steps: transfer of the commands of the protection function from a remote server (6) via a communications network (5) to the protection unit; loading of the commands in the protection unit and; execution of the loaded commands (14, 15, 16) of the protection function. Independent claims are also included for the following:- (a) a protection unit for an electrical power network and; (b) a sub-station of an electricity distribution network; (c) a computer program product.
Abstract:
The method involves a communications device associated with the system sending a report containing information related to the system and a validation code, extracting a control code from a message received after sending the report in accordance with a first extraction rule, checking if the message originated from a recipient of the report and extracting and implementing command information only in the event of a successful check. The method involves using a communications device (2) associated with the controled system (1) that transmits a report containing information related to the system and a validation code and extracting a control code from a message received after sending the report in accordance with a first extraction rule, checking whether the message originated from a recipient of the report and extracting command information in accordance with the first rule and implementing it only in the event of a successful check.
Abstract:
The transmission method involves using interleaving of the data blocks to be transmitted at the transmission side. Coded sub symbol sequences are provided used for modulation of a carrier frequency, with corresponding demodulation and de-interleaving at the reception end. A multi-carrier modulation method is employed for modulation of several channels via parallel sub symbol streams, obtained from the serial data stream to be transmitted.
Abstract:
The method applies to a machine (1) with at least one rotating body (2). At one measurement point on the machine at least a vibration measurement (x1-x4) is taken and at least one vibration parameter of the fundamental component (f1) and/or an harmonic component of the machine. In addition the fundamental frequency of at least one rotating body is detected and a nth amplitude An of an nth vibration of the machine is calculated according to the following equation :- An = (C2 + D2)0.5, Where:- With xm(t) an mth vibration measurement (x1-x4) of an mth vibration detector, m = 1,2,3,....T = 1/f1 = 2 x p/w and w the rotational frequency of the rotating body
Abstract:
This specification discloses an intelligent and digitalized process level interface which is referred to herein as an Intelligent Process Interface (IPI). The input of the IPI includes both analog and digital channels and therefore the IPI can be used for substations in transition or retrofit stages with both conventional and non-conventional primary devices. The IPI acts not only as a digitalized interface, but also as an intelligent supervisory and control unit for switching functions. The architecture of the IPI is flexible and allows for the functionality to be distributed to several devices.
