Overvoltage protection and voltage stabilization for Motion Control terminals
This application example describes how Motion Control applications with the output stages for servo, DC and stepper motors by Beckhoff are optimized by the utilization of buffer capacitors. The buffer capacitor terminals EL9570 for EtherCAT and KL9570 for K-Bus stabilize the voltage supply by absorbing the fed back energy and dumping the energy that the buffer capacitor cannot protect against i...
متن کاملHosting Capacity of the Power Grid for Renewable Electricity Production and New Large Consumption Equipment
After a brief historical introduction to the hosting-capacity approach, the hosting capacity is presented in this paper as a tool for distribution-system planning under uncertainty. This tool is illustrated by evaluating the readiness of two low-voltage networks for increasing amounts of customers with PV panels or with EV chargers. Both undervoltage and overvoltage are considered in the studie...
متن کاملCoordination of Overvoltage Protection in Low-Voltage Residential Systems
This paper was presented as a summary tutorial aimed at the French-speaking Canadian community to solicit their comments on the development of the IEEE Std 587 Guide. The paper has been translated into English by the author to make the English-speaking community aware of that paper, which served at that time as one output for the release of the extensive test results that were reported in the 3...
متن کاملOverload and overvoltage in low-voltage and medium-voltage networks due to renewable energy - Some illustrative case studies
This paper presents the use of curtailment to allow more wind or solar power to be connected to a distribution network when overcurrent or overvoltage set a limit. Four case studies, all based on measurements, are presented. In all cases the hosting capacity method is used to quantify the gain in produced energy for increased levels of distributed renewable energy resources. A distinction is ma...
متن کاملOver/Undervoltage and Undervoltage Shift of Hybrid Islanding Detection Method of Distributed Generation
The mainly used local islanding detection methods may be classified as active and passive methods. Passive methods do not perturb the system but they have larger nondetection zones, whereas active methods have smaller nondetection zones but they perturb the system. In this paper, a new hybrid method is proposed to solve this problem. An over/undervoltage (passive method) has been used to initia...
