Why automation is important in power plants
Automation in thermal power plants
INTIS has a part in the construction of a dozen thermal power plants and waste incineration plants in several countries. In these projects, engineers supplied the complete energy production automation software.
The automation system in a power plant ensures the adaptation of systems dictated by the electrical grid and the process energy system. This also provides optimal control in some of the modes like a start-up and shut down, and safety of the plant under all operating conditions.
The principles to manage the process control are,
Load control and frequency response: it is depending on the type of the plant, and it is responsible for variations in grid demand, and frequency is controlled using the gas turbine and burner management system.
Secondary closed control loops: it maintains process parameters like temperatures, levels, and pressures within permissible limits. Component-specific closed control loops: it ensures the operation safe of individual pieces of equipment. Such as pump minimum flow control and lubrication oil pressure control.
Automation systems in thermal power plant types are,
- Biomass power plants,
- fossil fuel-fired power plants,
- combined-cycle power plants,
- combined-cycle power plants,
- waste incineration plants.
In this automation system, we offer to complete the programming, engineering, equipment supply, testing, installation, and commissioning.
Thermal power plant automation
Internet of things is the new trend for industrial automation to producing quality products. Here the manpower at a low cost. The use of Distributed control system or programmable logic controller in thermal power plants, the parameters controlling such as temperature, pressure, and humidity is a critical and essential process and requires trained labor for the work.
Power plant automation
The technology has changed the purpose of the control room. Now here is one of several portals for an integrated team of experts with a common objective of maximizing the plant’s assets.
Control rooms are evolving
The automation systems include portals that allow people to access information around the world. The hardware and software designs to maximize the industry standard.
Automation systems are high standards for reliability. The power plant automation system is populated with input/output modules that meet standards for surge withstand capability, isolation, and environmental specifications. Remote terminations are external to the I/O modules that are to be with us in the future.
Off-the-shelf hardware solutions have resulted in lower prices for hardware such as Input/output modules and even controllers. When the value of s/w applications rises, the system shipments continue to fall. The technology is appropriate at any price. At this time, the different computer bus architectures have evolved and no single one is accepted than others. The acceptance by vendors is fast switched Ethernet, Profibus, Fieldbus, ASI, DeviceNet. The ability to supply products and services that enhance operations, increasing efficiency, and controlling emissions is a major requirement of the power industry.
An automation system designed to optimize the economics of plant assets. Here we required deregulation, greater awareness of optimizing operations. Maximizing efficiency, availability, and safety are important roles of an automation system. And reporting, monitoring, and controlling emissions have been elevated, in some cases to the highest corporate level.
The direct digital control systems offered graphical interfaces. The plant operations, maintenance, owners, and other specialists are to provide advice. Technology can enable interaction with remote location who has real-time access to information from a process plant.
The plant function includes, operation maintenance and management will be tightly integrated across all plant areas. The system will embrace the latest information and communication technologies will be incorporated. The interfaces of flexible and switchable are the heart of the systems.
The solutions for plant automation
The power demands increase then the pressure on plants worldwide, leading to technology. Most options are available for power plant automation.
Turbines, boilers, and generators have to operate reliably and safely during the hazardous start-up and low load operating levels.
The automation systems are in a transformational stage. These are now fast and network-enabled becoming communications. Channels provide real-time information to provide input to the decision-making process.
Large power plants are supervised and controlled by maintenance staff and production uses the process controlling system as a tool to automate the process functions.
Control loops used in power plants are,
- Superheater steam temperature control loop
- Drum level control loop
- The auto combustion control loop
- Bed temperature control loop
- Furnace inventory control loop
- Furnace pressure control loop
- The excess air control loop
