Overvoltage Suppression Method Based on Machine Learning for Motor Drive Systems

International Conference on Electrical Machines and Systems
This paper presents an overvoltage suppression method based on machine learning for motor drive systems. Overvoltage in motor drive systems causes electrical stress that leads to insulation breakdown in motors. This paper investigates the impact of cable

Optimization Scheme of STATCOM Parameters for Temporary Overvoltage Suppression

2024 4th Power System and Green Energy Conference (PSGEC)
The temporary overvoltage (TOV) issue arises more frequently in modern power system as the access of electronic power equipment nowadays. One main reason is the reactive power surplus generated by reactive power compensators such as STATCOM.

A hybrid active filter implementation of an overvoltage suppression scheme

2004 IEEE International Symposium on Industrial Electronics, 2004
In several practical applications actuators are interconnected to a controlled plant through long cables. If the actuator operates at a fast sampling rate (with respect to the propagation delay of the cable) and its impedance cannot be neglected, wave reflections occur and the transmitted pulse are deformed-degrading the control quality.

Overvoltage Suppression Method for Single-Inverter Dual-Parallel PMSM Drives Using a PWM Scheme

European Conference on Cognitive Ergonomics
This paper presents an overvoltage suppression method for single-inverter dual-parallel (SIDP) PMSM drives using a PWM scheme. The mechanism of voltage reflection is first examined in conventional single-inverter single-motor systems to establish a ...

Overvoltage Suppression and Energy Balancing for Sequential Tripping of Hybrid DC Circuit Breakers

IEEE transactions on industrial electronics (1982. Print), 2023
During sequential tripping of dc hybrid circuit breakers (HCBs), the energy-absorbing metal-oxide varistors (MOVs) are inserted one after the other rather than simultaneously.

Suppressing resonance in transformer winding under very fast transient overvoltage

2016 IEEE Innovative Smart Grid Technologies - Asia (ISGT-Asia), 2016
This paper presents a new method for suppressing internal resonance in power transformers connected to gas insulated substation (GIS) due to very fast transient overvoltage (VFTO) in the GIS. Internal resonance within the transformer windings will take place if one of VFTO frequencies matches with the power transformer natural frequency.

Load Rejection Overvoltage Suppression and Parameter Design Method of UHV AC Transmission Line

Electronics
UHV (ultra-high voltage) by instant AC transmission system is accompanied by huge reactive power transmission. When the load drops sharply, it is easy to produce serious power frequency overvoltage, which is also defined as load rejection overvoltage ...
