TECHNIQUES FOR CONTROLLING A POWER ELECTRONICS CONVERTER IN AN ELECTRIC DISTRIBUTION GRID - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18347381 Titled 'TECHNIQUES FOR CONTROLLING A POWER ELECTRONICS CONVERTER IN AN ELECTRIC DISTRIBUTION GRID'
Simplified Explanation
The abstract describes a controller used in an electric distribution grid to control a power electronics converter. The controller is designed to estimate the grid voltage based on the converter current in a passive operation mode. It also determines the operation mode of the converter and, when transitioning from passive to active mode, it estimates the grid voltage again based on the initial estimate and the converter current in the transition state. This estimation is done using a closed control loop.
Original Abstract Submitted
The present disclosure relates to a controller for controlling a power electronics converter in an electric distribution grid for distributing electrical energy, wherein the controller is configured to determine a first estimate of a grid voltage based on a converter current of the power electronics that the power electronics converter is capable of receiving in a passive operation mode, determine an operation mode of the power electronics converter, and upon determining a transition state of the power electronics converter in which the power electronics converter is transiting from the passive operation mode into an active operation mode, the controller is configured to determine a second estimate of the grid voltage based on the determined first estimate of the grid voltage and a converter current of the power electronics converter being receivable by the power electronics converter in the transition state upon a basis of a closed control loop.
