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...
متن کاملFault Diagnosis of On-Load Tap-Changer Based on Variational Mode Decomposition and Relevance Vector Machine
Abstract: In order to improve the intelligent diagnosis level of an on-load tap-changer’s (OLTC) mechanical condition, a feature extraction method based on variational mode decomposition (VMD) and weight divergence was proposed. The harmony search (HS) algorithm was used to optimize the parameter selection of the relevance vector machine (RVM). Firstly, the OLTC vibration signal was decomposed ...
متن کاملSolid - 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...
متن کاملDecentralized 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 ...
متن کاملImprovement of on-load tap changer performance in voltage regulation of MV distribution systems with DG units using D-STATCOM
This paper presents a new technique for the voltage regulation of a radial medium voltage (MV) distribution grid in presence of distributed generation (DG) units. The proposed technique consists of the coordinated action of on-load tap changer (OLTC) of transformer and reactive power compensation by D-STATCOM. Managing the system voltage using the action of OLTC is one of the most common ways f...
