SCADA HISTORY ARTICLE LINKS AND REFERENCES GUIDE

Brief History of SCADA system from various on-line sources and links

Below are some of the articles which talks about the brief history and development of SCADA (Supervisory Control And Data Acquisition) system.  These articles would be a great help for those who wants to know how and when SCADA system originated.

Evolution of SCADA (A Brief History of SCADA/EMS)
Supervisory Control, Data Acquisition, and Automatic Generation Control, were used in Electric Utility power system control for over sixty years. Each had separate beginnings, went through several evolutions in implementation, and eventually came together with Network Analysis and other functions to become computer based Energy Management Systems. This writing will attempt to trace their history and evolution from approximately 1950 to 2000.

History of SCADA (Supervisory Control And Data Acquisition)
Electric power systems as we know them began developing in the early 20th century. Initially, generating plants were associated only with local loads that typically consisted of lighting and electric transportation.If anything in the system failed — generating plant, power lines, or connections — the lights would quite literally be “out.” Customers had not yet learned to depend on electricity being nearly 100% reliable, so outages, whether routine or emergency, were taken as a matter of course.

The History of SCADA
SCADA systems became popular in the 1960’s as the need to monitor and control remote equipment grew. Early SCADA systems used mainframe technology and required human operators to make action decisions and maintain the information systems. Because this increased the human labor cost, early SCADA systems were very expensive to maintain. Today, SCADA is generally much more automated, and consequently more cost-efficient.

A Brief History of SCADA
SCADA Systems provide real-time monitoring and control of your facilities, and is an acronym for Supervisory Control and Data Acquisition. Its fundamental purpose is to remotely monitor a range of processes, collect real-time data and then perform analysis on the accumulated data. The foundation of SCADA can be researched back to the 1960's, when simple input and output devices were used to remotely monitor operations in industrial applications. Due to technology advancements, SCADA systems have now developed using advanced software, high performance microprocessors and wireless technology. Additionally, SCADA systems deliver productivity and operational efficiencies by improving the reliability and stability of your system.

The Evolution of SCADA/EMS/GMS (from ABB)
 SCADA/EMS/GMS (supervisory control and data acquisition/Energy Management System/Generation Management System) supervises, controls, optimizes and manages generation and transmission systems. SCADA/DMS (Distribution Management System) performs the same functions for power distribution networks. Both systems enable utilities to collect, store and analyze data from hundreds of thousands of data points in national or regional networks, perform network modeling, simulate power operation, pinpoint faults, preempt outages, and participate in energy trading markets.

PARTS OF A POWER TRANSFORMER

What are the name of the basic parts of a Power Transformer? We can not deny the fact that only a handful of electrical engineering students are presently familiar with power transformers especially on what it looks like. Unlike a transformer we found in our homes, a power transformer’s appearance and construction is somewhat more complicated. It is not just a simple winding with a primary and secondary terminal although basically any transformer has one. The function that a power transformer plays in an electrical system is very important that an electric utility can not afford to loss it during its operation. Our discussion here will focus more on the basic parts and functions of a power transformer that are usually tangible whenever you go to a substation . Although not all power transformers are identical, nonetheless they all have the following listed parts in which the way of construction may differ.

ELECTRIC MOTOR FRAME SIZE STANDARD SPECIFICATIONS

ELECTRIC MOTOR FRAME SIZE STANDARD SPECIFICATIONS How is electric motor frame size being specified? Motor frame dimensions have been standardized with a uniform frame size numbering system. This system was developed by NEMA and specific frame sizes have been assigned to standard motor ratings based on enclosure, horsepower and speed. The current standardized frames for integral horsepower induction motors ranges from 143T to 445T. These standards cover most motors in the range of one through two hundred horsepower. Typical example of where you can locate the frame is shown in Fig 1.2.D – Frame No. The numbers used to designate frame sizes have specific meanings based on the physical size of the motor. Some digits are related to the motor shaft height and the remaining digit or digits relate to the length of the motor. The rerate, or frame size reduction programs were brought about by advancements in motor technology relating mainly to higher temperature ratings of insulating mate

ELECTRIC MOTOR NAMEPLATE SPECIFICATIONS

How do we interpret an electric motor nameplate? Motor standards are established on a country by country basis.Fortunately though, the standards can be grouped into two major categories: NEMA and IEC (and its derivatives). In North America, the National Electric Manufacturers Association (NEMA) sets motor standards, including what should go on the nameplate (NEMA Standard MG 1-10.40 "Nameplate Marking for Medium Single-Phase and Polyphase Induction Motors").
