Decentralized tap changer blocking and load shedding against voltage instability: prospective tests on the RTE system

This paper reports on prospective tests of a system protection scheme against long-term voltage instability relying on a set of distributed controllers, each monitoring a transmission voltage, blocking tap changers and shedding loads in a zone. The emergency actions adjust in magnitude and location to the disturbance. Each controller acts in closed-loop, which guarantees robustness. The method ...

Innovative Transformer Load Tap Changer Control Using Ethernet-Based Communications

This paper describes the design of a load tap changer (LTC) control for up to four parallel transformers using a modified circulating current approach. The LTC control discussed in this paper was implemented using programmable logic, math functions, and IEC 61850 communications over fiber-optic Ethernet. One LTC control is associated with each transformer. The current angle from each LTC contro...

Solid - State On Load Tap - Changer for Transformer Using Microcontroller

The on-load tap changing (OLTC) regulators have been widely used since the introduction of electrical energy. They ensure a good regulation of the output voltage in presence of large variations of the input voltage with typical response time from several mili-seconds to several seconds. Earlier mechanical type of on load tap changers were into practice. But they had considerable limitations and...

On-line Local Load Measurement Based Voltage Instability Prediction

Voltage instability is a major concern in operation of power systems and it is well known that voltage instability and collapse have led to blackout or abnormally low voltages in a significant part of the power system. Consequently, tracking the proximity of the power system to an insecure voltage condition has become an important element of any protection and control scheme. The expected time ...
