A method for controlling circuitry of a softstarter arrangement to operate an electric motor for driving a pump is provided, wherein the softstarter circuitry electrically connects the motor to electric mains. The method includes: (i) controlling the circuitry of the softstarter arrangement to accelerate the motor up to full speed in a forward direction; (ii) controlling the circuitry of the softstarter arrangement to decelerate the motor when the motor has run at full speed in the forward direction for a first period of time; (iii) controlling the circuitry of the softstarter arrangement to accelerate the motor up a specified speed in a reverse direction; (iv) controlling the circuitry of the softstarter arrangement to decelerate the motor when the motor has run at the specified speed in the reverse direction for a second period of time; and (v) repeating the steps (i)-(iv) one or more times.

Automatic cleaning method for a pump system comprising a softstarter arrangement

A method is disclosed for configuring an intelligent electronic device (IED) that includes enabling dynamic capability of the IED by a flexible data modeling technique to dynamically adapt a data model based on an application requirement using a configuration tool. A substation automation system is also disclosed which includes a local system equipment having a plurality of IEDs associated with the local system equipment and an IED configuration tool configured to interact with the firmware of each IED to configure the IED based on application requirements. The application configuration tool can include dynamic capability information of the IED to enable a flexible data model in the IED.

Method for configuring an intelligent electronic device and a substation automation system

A method, a substation automation apparatus and an intelligent electronic device (IED) are disclosed which are, for example, not limited only to publishing data (data emanating) from the IED. An exemplary method includes assigning a unique identifier to one or more data fields, where the one or more data fields is associated with a short address attribute in the data emanating from the intelligent electronic device; and dynamically updating the identifier based on user specific configuration data by an IED application configuration tool. The IED can include a list of functions; (e.g., each function being represented as a logical node; and each logical node containing data objects); and a flexible addressing scheme for configuring the data objects and publishing data from the IED, but not only data emanating from IED.

Method and system for publishing data from intelligent electronic devices

An intelligent electronic device for a Substation Automation or Distribution Automation system as well as to a method and computer program product for providing it. The device has a structuring of its own functionality according to a communication standard and includes mechanically separable, replaceable hardware modules interconnected via an inter-module bus. The modules implement functionality related to function related elements of the standard and include a communication module and I/O modules. The device includes elements of the communication standard comprising one device related element and replaceable function related elements of all the functions provided by the modules. The communication module includes the device related element and function elements associated with the function of the communication module as well as functions provided by all the I/O modules.

Flexible intelligent electronic device

An electrical process interface device for provision in a low control and protection level of a Substation Automation or Distribution Automation system; the device includes a process interface unit for interfacing the electrical process at the low control and protection level, which unit has a number of parallel data connections on which I/O data related to control and protective devices on higher control and protection levels may be transmitted. The device also includes a signal conversion unit connected to the data connections, which unit packets data of the data connections according to a communication standard used by control and protective devices on the at least one higher control and protection level for allowing data to be directly transmitted between the electrical interface device on the low control and protection level and other devices on higher control and protection levels.

Electrical process interface device

An intelligent electronic device and a method for activating a function in an intelligent electronic device; the device includes an inter-module bus, a first interface and a number of hardware modules connected to each other via the inter-module bus. The modules include a process control module including a control unit that senses the types of hardware modules connected to the inter-module bus, that obtains set-up data from an external portable data carrier, where the set-up data includes configuration data and verification data, where the verification data includes hardware type data related to the modules in the device, that compares the obtained verification data with own verification data including data regarding the sensed hardware type, and that activates a protection function only if there is a match between all verification data being compared.
