Various inductive loads used in all industries deals with the problem of power factor improvement. Capacitor bank connected in shunt helps in maintaining the power factor closer to unity. They improve the electrical supply quality and increase the efficiency of the system. Also the line losses are also reduced. Shunt capacitor banks are less costly and can be installed anywhere. This paper deal...

Harmonics in electrical networks occur as a result of non-linear loads. It has an effect on power factor improvement using capacitors in terms of increasing the unbalance current between units. In addition, the occurrence of resonance and result in the exit of capacitors from service by the protective relays to protect the units from collapse. The main objective of this research is the real-tim...

The advanced traction power supply system (ATPSS) is a new directional development for traction power supply systems, which can totally remove the neutral sections and effectively promote power quality. However, the existing converters suffer from small substation capacity. In this paper, a new configuration based on a three-level neutral point clamped (3L-NPC) three-phase to single-phase casca...

The North American power grid is one of the most complex technological networks, and its interconnectivity allows both for long-distance power transmission and for the propagation of disturbances. We model the power grid using its actual topology and plausible assumptions about the load and overload of transmission substations. Our results indicate that the loss of a single substation can resul...

The XML technology currently widely used in network communication is also able to play an important role in the automation system of the power system. Based on some specifications and standards of the current power system, the study conducted self-description of the information and data modeling of substation communication protocols with XML and its object-oriented technology, and discussed bas...

The goals of this project are to develop rehabilitation strategies and enhance seismic design guidelines for key equipments in power substations, which are one of the most critical facilities in a power system. Furthermore, it will provide the knowledge base to be integrated into the overall loss estimation model for the entire power network. To achieve these goals, key substation equipments ar...

For a primary substation (P/S), there are many typical methods to control voltage and reactive power such as adjusting the generator mode, switching shunt capacitor (SC), adjusting on-load tap changer (OLTC), and switching shunt reactor (SR). In this study, a graphical user interface (GUI) is designed combining with nine-area diagram to observe the relationship between voltage and reactive powe...

To help make the power system more reliable huge amount of data generated from different Intelligent Electronic Devices (IEDs) located in substation of power system should be collected, analysed and displayed. Easy way of accessing and viewing recorded data or information obtained through automated analysis is commonly lacking in the existing power systems. Nowadays data and related information...

In this paper, a novel framework is proposed to study impacts of regulatory incentive on distributed generation (DG) investment in sub-transmission substations, as well as upgrading of upstream transmission substations. Both conventional and wind power technologies are considered here. Investment incentives are fuel cost, firm contracts, capacity payment and investment subsidy relating to wind ...
