Types Of Scada System

Scada Systems

Scada remains for 'Supervisory Control and Information Securing' [1]. The fundamental capacity of Scada is securing information from remote gadgets and giving remote control from a Scada Host programming stage. It provides neighbourhood control with the goal that the gadgets may turn on and off at the opportune time when required. It underpins the control procedure and technique for catching information and occasions remotely to monitor these procedures. Host framework additionally gives diverse capacities to disturbing, graphical presentations and great verifiable stockpiling of information. Over the most recent couple of years Scada frameworks have gained great ground as far as usefulness, transparency and its field of activity has likewise extended in late couple of years. The execution of Scada stage is enhancing everyday fathoming number of normal issues and issues. As the stage is presently being utilized as a control framework at numerous spots twisting the perplexing control frameworks as those of material science tests.

Types of Scada System

1. Monolithic SCADA systems - primary, backup connected with mainframes to achieve redundancy [1].
2. Distributed SCADA systems – multiple systems connected with LAN and control is shared [1].
3. Networked SCADA systems – communicate through WAN over data lines [1].
4. Internet of things technology, SCADA systems – communicate through cloud computing which reduce its infrastructure cost [1].

Applications

1. Manufacturing ventures [2].
2. Waste Water Dispersion Plants [2].
3. SCADA is used in power frameworks [2].
4. Oil and Gas Trans & Distributions [2].
5. Wind Power Generation [2].
6. Communication Networks [2].
7. Industrial Plans and for Process Control [2].
8. Mass transit and Railway Traction [2].
9. Traffic Signals to control traffic [2].
10. Buildings, facilities and environments i.e. control systems [2].

Objectives

1. System Efficiency
2. Increased Penetration energy resources
3. Reduced energy requirements in transmission and generation
4. Increased relativity of sequence of loads

Functions

1. Act as an Communication network
2. Sensors
3. SCADA as master units
4. Act as Remote Telemetry units
5. User Interface
6. Monitoring
