Abstract:
The invention relates to automatically commissioning of devices of a networked control system, particularly to automatically commissioning of wireless switches in lighting control systems. A basic idea of the invention is to derive from an installation constraints with regard to a networked control system and to consider these constraints during an automatic commissioning process based on signal strength processing. This may help to improve the reliability of commissioning based on signal strengths. An embodiment of the invention relates to a method for automatically commissioning of devices of a networked control system, which comprises one or more first devices (S1-S3) and several second devices (RC1-RC3) being able to communicate wirelessly, wherein wireless signals from first devices (S1-S3) are received by one or more second devices (RC1-RC3) and for each received wireless signal the signal strength is determined, and wherein the commissioning comprises the following steps: processing the determined signal strengths considering constraints derived from an installation of the networked control system for commissioning, and assigning the first devices (S1-S3) to one or more of the second devices (RC1-RC3) depending on the processing result.
Abstract:
The invention relates to a disaggregation apparatus (1) for identifying an electrical consumer in an electrical network (2). An electrical signature providing unit (7) provides electrical signatures of the electrical consumers (4, 5, 6),and an electrical parameter determining unit (8) determines an overall electrical parameter of the electrical network (2). An identification unit (9) identifies an electrical consumer depending on the determined overall electrical parameter and a correlation of the electrical signatures. Since the identification unit identifies an electrical consumer depending on the determined overall electrical parameter and a correlation of the electrical signatures, the identification of an electrical consumer does not depend on the detection of an event only. This makes the identification more robust, especially less prone to errors caused by missed events, thereby improving the reliability of identifying an electrical consumer in the electrical network.
Abstract:
The invention relates to a method for identifying the status of appliances connected to an electrical installation, for example a status indicating whether the appliance is ON or OFF. The identification is obtained by measuring one or more electrical values from the electrical installation such as voltages, power and current in various forms. The measured values are compared with previously obtained appliance signatures in order to obtain a match with one of the signatures. A positive match is used to set a status of one of the appliances. A status may be the current power consumption or the power consumption may be determined subsequently from the status. Since appliance signatures may depend on the supply voltage, a signature may contain a plurality of supply voltages and an electrical parameter, e.g. power consumption, for each of the voltages. The signatures may be obtained during a training process where the voltage supplied to the appliance is varied in a controlled way.

Abstract:
The present invention relates to a method and apparatus for disaggregation of energy consumption in a power distribution system. The basic idea is to look at the overall energy consumption and recognize the contributions of each single electrical device (120), e.g. for the purposes of providing a breakdown of energy consumption to users. Disaggregation is assisted by usage of multi-modal system data coming from various external data sources (106-1 to 106-n), such as building management systems and/or IT infrastructure, to relate activities of people or devices to changes in power consumption.
