This paper describes about the grid switch control system. The aim of the project is to provide a facility by which we can control the two power sources in the power grid. The purpose of the project is to provide a flexible system by which we can control the two DC power sources. Now days, there is a lot of requirements to control the appliances in an industry or in a home connected to the power grid when we are working. The main aim of the present project is to provide a facility by which we can control the DC power sources connected to the power grid. The only thing is we need to switch the button for a control board to the power control section. The control board which is attached to the power grid control section in the industry. This receives the commands to the microcontroller whenever there is a power cut from the main source. The microcontroller plays a major role in receiving the commands from the main source module and to switch from a Main DC source or from a Battery DC source which is fed to thee DC generator (Wind energy). The particular source is switched according to the command. Here in this project a power grid is connected to motor control unit. The project implements the design of a system by which we can control the power grid of two DC sources.

A system of ink key remote controling is introduced, which is consisted of work station control system and motor control system. The ink key work control system is based on S3C2440A platform and the motor control system use microcomputer STM32VET6 as central control unit. The system uses TCP/IP protocol as the communication protocol while the Ethernet provides the corresponding physical layer . Thus the system can control multiple large-scale printers.The system can directly access the public network to send and receive data when necessary, greatly improving the convenience of the system.

The SkyTrakker™ is a highly accurate and highly efficient parabolic trough control system. The system includes the microprocessor control board, separate motor controller, and sensors (temperature, position, hydraulic pressure). The SkyTrakker™ has several distinct advantages and design features that provide better manufacturability, shorten installation time, and reduce O&M cost. Some of the advantages and features are: 1. Maximum control and performance with reduced parasitic power consumption. 2. Lower motor input power consumption during deploy, tracking and stow (the SkyTrakker™ uses 52% of the power consumed at NSO). 3. Simple 110v AC single-phase motor requirements with digital motor interface to reduce parasitic power consumption at motor start-up and during tracking. 4. Local or remote monitoring and control. 5. Separate motor control providing a high level of motor power isolation from the electronics. 6. Microprocessor based control board offering fast response, monitoring of HTF temperature, SCA position, hydraulic pressures, and control of the motor. 7. Enhanced field diagnostics to isolate position sensor and motor control problems and provide run-time status of operation. 8. Accurate tracking using virtual tracking algorithms, eliminating the use and maintenance of sun sensors. The SkyTrakker™ control system is modular and designed for quick assembly and installation at the SCA pylon. The major sub-system parts (control board and motor controller) are pre-assembled and are mounted on a pre-wired mounting panel. The NEMA 4 electrical enclosure can be mounted to the pylon with or without the internal pre-wired panel, providing installation flexibility when building the field. All control system components (control board, motor controller and sensors) can be easily replaced in the field. And motor life is greatly extended due to reduced overall power and reduced parasitic power consumption.

Space availability is one of the major parameter to be considered for structuring a control system. The control system installation occupies space for motors, control circuits, wiring connection and driver units. The motive of this work is to minimize the space requirement for a motor control system by making a wireless communication between the motor driver unit and control unit. The design saves the space requirement for control circuit wiring and control circuit unit. The design is helpful in minimizing the overall space requirement of the motor control system. As the control unit is made with wireless communication, the control unit can be moved anywhere near to the system. This improves the accessibility of the system at fault rectification time and precise operation time. The result indicates the reliability and efficiency of the proposed system with various parametric evaluations.

With renewable power sources and new topology structures being widely introduced into the power system, the current local information-based power generation-side protection cannot fully guarantee the protection performance and the safety coordination with the power grid. This paper proposes an improved hierarchical protection system on the power generation-side. The proposed system takes advantage of the fusion of multi-information provided by the system, station and local layers. The system layer provides the information such as system voltage control and power regulation demand, so that the generation-side protection and control system can adapt to the system operation mode and power regulation demand. The station layer realizes the coordination of the protection principle and action strategy among the related units through information interaction with the power grid, the automatic control system and the local layer protection. The local layer introduces the condition monitoring information and more abundant protection information to enhance the protection performance and master the generation units’ safety condition. To illustrate the hierarchical protection system construction method and actual application mode, the multi-information fusion-based comprehensive local layer protection method and the multi-generators information fusion-based hierarchical protection method are taken as examples. Case analysis shows that the proposed methods can reflect more slight internal fault forms and can adaptively determine the protection action characteristic and tripping strategy according to the system operating conditions and other generators’ fault conditions, which effectively improve the protection sensitivity and coordination capability. To provide reference and inspiration for follow-up research, the hierarchical protection system construction mode, communication technology and research approaches of new protection methods are further pointed out.

This study implements the auto start control system on an electric motor 3 phase C4Feeding pump when the discharge pressure is low-low (4.3 kg /cm²). The C4 feeding pumpmotor was initially manually operated from the local control station, this was very ineffectiveand inefficient because it still relied on the field operator to operate the pump motor and whenthe plant was in normal operating it is very risk if the field operator late to operate motor then itwill impact to quality of the product, and if the delay time to operate motor is too long then planthave to shut down, therefore improvement is needed in the C4 feeding pump motor controlsystem. In this paper, various types of 3-phase motor control are explained which allow it to beapplied to the C4 feeding pump motor that are on-off, inverter, and variable speed drive andefficient selection of the three systems control of the motor. Software and hardware used in thisthesis work are DCS CENTUM VP Yokogawa.
