Highly integrated monitoring system solution/(Australia’s largest power plant)
Application location: New South Wales, Australia
Contract date: 2003
Completion date: August 2004 to 2005
Industry: Electricity
Implementation Summary
1. Faster deployment
The replacement of control systems for the four generator units is still ongoing. The first two units have been completed ahead of schedule and have been very successful, providing customers with tangible benefits.
2. Efficient operation ensures high reliability
The updated unit operates more stably and efficiently, and compared to the previous control system, the new system helps customers respond faster to daily load changes.
3. The maintainability of the system has been improved
Real time and remote maintenance of on-site equipment provided by various suppliers is carried out through control systems and comprehensive equipment management systems, helping customers minimize daily maintenance workload.
background information
The Erasing power plant is located in the northern part of Sydney and is one of the largest power plants in Australia, with four 660MW coal-fired units.
The power station has been in operation since 1981 and has been operating steadily ever since. In order to ensure continued stability in the coming decades, the owner of the power plant, Erring Energy Group, has decided to adopt a modern integrated monitoring system (ICMS) to replace the original hardwired control equipment. The main driving force behind this decision is the requirement to maintain stable factory operations and achieve operational improvements, with the aim of ensuring that the group maintains a competitive position in the deregulated Australian electricity market. This equipment update project began in early 2003, under the guidance of Yokogawa Electric Australia and in collaboration with TechComm Simulation, a wholly-owned subsidiary of Yokogawa Electric.
Challenges and Solutions
The customer needs a comprehensive system to control the operation of boilers, turbines, generators, and other power plant equipment. To this end, Yokogawa Electric has proposed a complete solution, which includes a distributed control system (DCS), factory information management system, on-site equipment management system, fully realistic training simulator, and on-site equipment that can receive strong local support.
