SCADA Control

=Purpose= (1)	Learning the principle and operation of Synchronous motor generator and SCADA Control system. (2)	Using PC software (which is little relative to the Programmable Logic Controller) to control the rotation speed of the generator. (3)	Able to adjust speed and frequency of the motor,and show the rotate frequency of the Synchronous motor in the scope successfully.

=Background=

The UI Department of Electrical and Computer Engineering laboratory facilities include an analog model power system (AMPS) that is capable of simulating interaction of control and protection hardware in a network with up to five lines transmission line segments. The system protection hosts a full complement of commercial protective relays and a fault generator capable of initiating common fault types with any fault impedance and any duration. Multiple generation sources can be interfaced with the system including synchronous machines, a doubly fed induction generator and power electronically coupled generation.The facility shown in Figure 1 is used for labs for several power systems courses as well as for research projects.

The model power system has controls to control a synchronous generator for manual synchronization to the Avista system through the building power supply. The manual controls include push buttons for start and start and potentiometers to control speed and terminal voltage as shown in Figure 1. The potentiometers regulator a dc control signals for the MG set. There is also a synchroscope for visual indication to determine when to manually close the circuit breaker. While the circuit breaker can be remotely controlled through a supervisory control and automation (SCADA) interface, the machine itself cannot be controlled through SCADA.

=Concept Selection=

Step motor
1.	Stable. Can drive a wide range of frictional and inertial loads. 2.	Needs no feedback. The motor is also the position transducer. 3.	Inexpensive relative to other motion control systems. 4.	Standardized frame size and performance. 5.	Plug and play. Easy to setup and use. 6.	Safe. If anything breaks, the motor stops. 7.	Long life. Bearings are the only wear-out mechanism. 8.	Excellent low speed torque. Can drive many loads without gearing. 9.	Excellent repeatability. Returns to the same location accurately. 10.	Overload safe. Motor cannot be damaged by mechanical overload.

Human Machine Interface(HMI)
1.	Deliver efficient HMI solutions by building effective operator interface screens through easy-to-use tools without the need for mapping data tags. 2.	Identify changing system conditions and make informed decisions based on real-time analysis without the need of any special software to view the HMI. 3.	Leverage powerful and reliable RTAC hardware with a cost-effective HMI option for local/remote monitoring, control, integrated alarms, and annunciation. 4.	Monitor your system and analyze performance anywhere, anytime with a secure, web-based, thin client user interface, which Including morphological charts, decision matrices as appropriate 5.	Access the RTAC HMI locally or remotely via a web browser interface from the web server on the RTAC unit. On demand visualization and control makes monitoring and controlling your system a more efficient task. Role-based accounts provide appropriate security access. Since it is a thin client, no installation and no upkeep for a specific application are required. 6.	The RTAC HMI offers an easy way to visualize data and create custom diagrams to monitor and control your system. The HMI provides authenticated access for multiple users from multiple locations and is viewable from a web browser. It renders natively on browsers compatible with HTML5 web standard—no plugins required.
