With the government's emphasis on environmental issues of power transmission and transformation project, noise pollution has become a prominent problem now. The noise from the working transformer, reactor, and other electrical equipment in the substation will bring negative effect to the ambient environment. This paper focuses on using acoustic software for the simulation and calculation method...

Power management is an important constraint in the design of various loads in industries for automation. So if power consumption increases then the substation monitoring is very important for the purpose of controlling the hardware and software optimization with the help of PLC ladder logic system and SCADA were used. This technique in order to reach strong conclusion about their actual impact ...

With ongoing efforts to make the power grid smarter, there is a large emphasis on the automation and data analytics. Substation automation is a key enabling technology for online monitoring, diagnosis and prediction for the health condition of the substation assets. Circuit breakers (CB) are one of the most vital components in a substation for tripping action required during the fault occurrenc...

Circuit breakers can fail to interrupt fault current when the power system has transient recovery voltage (TRV) characteristics that exceed the rating of the circuit breaker. There were two incidents of failures of outdoor switchgear at a power plant substation. The cause of the failure for these breakers was investigated in order to determine if transient recovery voltage is a contributing fac...

A new mathematical model for the multistage distribution network expansion planning problem considering reliability is proposed in this paper. Decisions related to substation and branch are driven by minimization of total cost, which comprises investment operating costs including impact reliability. The features two main novelties. First, a set novel algebraic expressions devised standard index...

Generation expansion planning is a challenging problem due to its large-scale, long-term, non-linear, and discrete nature of generation unit size. Since the computation revolution, there are several emerging techniques proposed to solve large scale optimization problem. Many of these techniques have been reported to use in generation expansion planning. This paper will describe these emerging o...

1. Project goals and objectives This project aimed at developing analytical models and methods for assessing the seismic response of electrical substation equipment connected by assemblies of rigid bus (RB) and flexible strap connectors (FSC) or slider connectors (SC). Also developed is a method to estimate the reliability of electrical substation systems subjected to stochastic earthquake load...

This document describes the utilization of the nonconventional measurements and advanced features of IEC 61850 standard for substation automation systems, especially how sampled value sending according standard part 9-2 can be used between IEDs in mediumvoltage substation to improve the reliability and functionality of the system. Calculated results indicate improvements on availability, perfor...

Transmission network expansion planning (TNEP) is an important component of power system planning. Itdetermines the characteristics and performance of the future electric power network and influences the powersystem operation directly. Different methods have been proposed for the solution of the static transmissionnetwork expansion planning (STNEP) problem till now. But in all of them, STNEP pr...
