Emerson intelligent wireless network monitoring saves costs for ppl power plant

editor's note: on December 15, Emerson Process Management's intelligent wireless technology provided ppl power plant with continuous performance data about the critical boiler feed pump of Montour power station and the feed water and air heater of Brunner Island Unit 1. Self organizing wireless technology helps to improve the reliability of the power station, It saves 50% of the cost while monitoring the feed pump and heater

Austin, Texas, USA (2008 touchscreen, USB, Bluetooth interface and other functions are also applied, December 15, 2008) - Emerson Process Management's intelligent wireless technology has proved its high cost-effectiveness and reliability by providing ppl power plant with continuous performance data about the critical boiler feed pump of Montour power station and the feed water and air heater of Brunner Island Unit 1 Murach Joe, Emerson's director of device reliability, said, "the additional information provided by wireless devices can help us monitor the mechanical and thermal performance of these important devices more effectively."

previously, because key temperature and pressure measurement data were not available, the software that can be used for thermal performance analysis and preventive maintenance plan cannot be widely used. The management of the company has always wanted to obtain this information, but the high wiring installation cost is an insurmountable obstacle. "Wireless is the only way to get the data you need," Murach said

Emerson intelligent wireless technology was selected for field demonstration in a power plant with dense infrastructure, and the results proved that it has reliable data transmission capability. Later, Montour power plant installed Rosemount wireless transmitter to monitor the vacuum pressure and differential pressure of the vacuum pulp screener and other measuring points that provide important parameters for the overall performance of the feed pump

the intelligent wireless network installed in Brunner Island factory includes wireless measurement function, which can effectively help determine the thermal efficiency of feed water heater and air preheating system. More than 25 wireless transmitters are widely distributed around the water supply and air heating systems. These measuring points are added to the factory history and its reliability monitoring software

"Emerson's technology can be applied to power plant environment" mura Liang explained that the sample was low ch. "Even if we bypass several floors and walls, the communication between the transmitter and the switch is still no problem. Using wireless technology, we don't have to drill holes in the deck, install pipes and cable trays, or pull wires. On the contrary, we have an easy to install, cost-effective and reliable wireless network. "

in the self-organizing network of ppl power plant, each wireless device is a router for the devices near it. Once the information encounters obstacles, it will re find the path until it is clear that the path to the intelligent wireless switch is only used for inspiration. When the conditions change or encounter new obstacles, such as temporary scaffolding, new equipment or parked building trailers, the self-organizing wireless network simply finds new ones Path to convey information

all these are automatically executed without any participation of users. The self-organizing network can provide path redundancy, and it is more reliable than the point-to-point communication between the communication equipment and the switch, which directly and simultaneously shows a good repeated scratch self-healing function. This technology optimizes the reliability of data while reducing power consumption. For the establishment of a successful wireless network, self-organizing network also reduces a lot of workload and the need for infrastructure

Murach said, "we are now able to monitor the condition of important assets such as feed pumps in greater depth and determine the thermal efficiency of key equipment. The latest information enables us to optimize boiler efficiency and detect problems in advance. This enables our maintenance personnel to seize the best opportunity for maintenance, rather than waiting for accidents. "
