Method of detecting state of power cable in inverter system
A method of detecting the states of power cables in an inverter system supplying power generated from an inverter to a motor by using three phase power cables is provided. The method includes: calculating the location of a current space vector for a first period when the first period arrives; using...

Summary: | A method of detecting the states of power cables in an inverter system supplying power generated from an inverter to a motor by using three phase power cables is provided. The method includes: calculating the location of a current space vector for a first period when the first period arrives; using the calculated location of the current space vector for the first period to calculate the predicted location of the current space vector for a second period; calculating the actual location of the current space vector for the second period when the second period arrives; comparing the calculated predicted location with the actual location; and detecting the states of the three phase power cables according to a comparison result. |
