Presents a collection of slides covering the following topics: power frequency optimisation; offshore wind farm; wind turbine; HVDC; substation; transformers; shunt reactor; switchgear; and converters.
The basis for the coordination of equipment in unit substations by assisting in the selection of components is intended as the use of this guide. A variety of designs for unit substations are possible using various combinations of incoming sections, transformer sections, outgoing sections, and transition sections. It is intended that the incoming, outgoing, transformer, and transition sections included...

Distribution transformers are found in secondary substations, and connect to three phase low voltage lines that deliver electricity to points of supply. Electricity customers are charged for their consumption based in the measurements registered in meters present at the point of supply. (PLC) signal injection in key element in PLC signal PRIME is a narrowband PLC band, used by utilities to Power Line...
The full regeneration of the braking energy is one of the most promising sources of energy savings to transport system operators. This paper presents the outcome of a RailEnergy cooperative research program focusing on reduction of energy consumption in transport systems. Today, urban transportation systems are generally fed at 750 Vdc or 1,500Vdc via rectifier bridges and trains are equipped with...
On shore oil and gas power systems networks are the heart of any exploration, drilling, transportation, and refining operation. With increased demand for product and project schedules increasingly shortened, new methods for maximizing uptime and project expediency have become necessary. In remote locations where contract and commissioning resources are limited, organizations need the ability to operate...
Online partial discharge (PD) monitoring systems are traditionally installed at a single mediumvoltage (MV) cable connection between two ring-main-units (RMUs). It is more efficient to monitor two or more consecutive cables using a single monitoring system. Moreover, practical experience with the PD-OL system, shows that for substations, with many parallel MV cables, and RMUs installing the inductive...
The paper summarizes produce over voltage principle of 110 KV main transformer central point and problem in protect mode, suggest has grounding protection of low reactance and this method could protect main transformer in 110 KV transformer substation effectively.
This paper presents a voltage/reactive power global optimization control method in the substation by adaptive ant colony algorithm. It can dynamically adjust pheromone updating strategy and probability of paths selection according to the distribution uniformity of solutions in the optimal process. This method, comprehensively considering the voltage of low-voltage side, the reactive at high-voltage...
This paper proposes a simple and practical method for determining the optimal acoustic noise levels of transformers to be replaced in an aged substation. The proposed algorithm is based on a reverse calculation method and Linear Programming using an empirical formula for estimating noise levels at the boundary points around the substation premises. Necessary input parameters are three dimensions of...
