Polyphase line filter

Abstract

A method of executing a bag of tasks application in a cluster over a distributed computing system, the cluster having a cluster resource manager. The method includes requesting that the cluster resource manager authorize access by a remote user of the distributed computing system to any idle nodes of the cluster, submitting a bag of tasks slave process to the cluster resource manager, loading the bag of tasks slave process in one of the idle nodes without an allocation operation, sequentially scheduling tasks from the bag of tasks to the bag of tasks slave process, and executing the bag of tasks slave process either until finished or until the node in which the bag of tasks slave process is loaded is required owing to a local allocation request.

Description

technical field [0001] The present invention generally relates to a polyphase line or mains filter, and more particularly to a passive harmonic filter as a front end of a non-linear consumer or load. Background technique [0002] In power grids or power mains, especially in the field of drive engineering, a large increase in the proportion of high-power electronics means an increase in distortion of the supply voltage due to the higher harmonic content of the current. In order to avoid harmonic currents in the grid, European standards have been issued in recent years that clearly define the guidelines for some manufacturers of electrical and electronic equipment. [0003] Different manufacturers around the world have different active and passive solutions to comply with published standards, guidelines and recommendations. Depending on the power and application of the equipment, or the usage of the equipment by the customer, these solutions have both advantages and disadvant...
