Automatic Active phase selector

This section gives the details and specification of the hardware on which the system is expected to work.

These include the user interface, services, domain objects and database. For the scope of this document, the database module is called directly by the service modules as appropriate, and will not be extracted as a core module for description. In figure 7, these are highlighted as dependenceies, with the added interaction of the user in the user terminal.

The objective of this lab is to be able to understand how the CPU functions work, as well as understanding machine and assembly language.

1. Use of phase gate model and project management tools same as traditional. On top of this, the Primavera software was used for the scheduling of the project.l

Abstract— Over-current in a power system is a situation when a larger than rated electric current exists through a conductor, leading to excessive generation of heat, and the risk of fire or damage to equipment Possible causes for over-current include short circuits, excessive load, incorrect design, or a ground fault. This paper presents the design and implementation of a microcontroller-based overcurrent relay for safe, reliable and efficient operation of power systems. Automated overcurrent protection is done by programming a Arduino (microcontroller) with standard ABB moderately inverse relay characteristics where the relay operates automatically in a permissible time whenever there is an over-current (abnormal or fault condition) in a power system [2].

After passing through these stages, an agreement is made before continuing to the design stage. Here all inputs/outputs, hardware/software for the new systems is designed. The creation and editing of the interfaces, codes and reports are worked.

Note: All the readings and calculations are performed at “outside station”. It uses the control Logix platform utilizing a GuardLogix safety PLC.

This report covers the real-time system design and the different components of the SCADA Energy Management System. Specifically, this report will focus on the General Electric XA/21 SCADA system and how it all fits together and how it provides a solution to end-users and administrators. The XA/21 is a very scalable and customizable system and that will be described at great length in this report (General Electric, 2013).

The aging of the available infrastructure and increased demand has caused the power supply voltage to become unstable. As a result, there is a need to implement emergency control actions, to prevent blackout (a country-wide power system trip) (Eskom).

The workshop and the course have been completed under my supervision to my satisfaction at the ‘Saffrony Institute of Technology, S.P.B. Patel Engineering College’.

This is to certify that the seminar report entitled “Hyperloop” submitted by Mr. Rushi Patel (14BEE093) & Mr. Romil Patel (14BEE092), students of B.Tech, 4th Semester towards the partial fulfillment of the requirements for the award of the degree in Bachelor of Technology (B.Tech) in Electrical Engineering of Nirma University is the record of work carried out by him/her under my supervision and guidance. The work submitted has in our opinion reached a level required for being accepted for examination.

The main hardware prototype parameters of the four 2-level VSIs and six-phase R-L impedance load are given in Table 2. For simplicity in implementation, experimental tests are carried out by two DSP TMS320F2812 processor, each one controlling two three-phase inverter (H and L) in open-loop scheme with six-phase R-L impedance load in open-ends con¬figuration [24-26].

During paralleling two synchronous generators, some conditions are needed to be fulfilled. Each of the three phases must have exactly the same voltage magnitude and phase angle as the conductor to which it is connected. To achieve this match, the following conditions must be met.

In this section we will emphasize on detailed overview of each of the block shown in previous block diagram. In every description of the block respective schematics and working is explained.
