Application: Voting Logic Panels
Installation Area: Hartlepool and Heysham 1, UK
Hima-Sella was awarded a contract by AMEC to supply 4 Voting Logic Panels for use at Hartlepool and Heysham 1 power stations. Two Voting Logic Panels were supplied to each of the power stations.
The panels monitor critical flooding levels in specific situations and show status indications. They automatically shut down the appropriate pumps in the event of pre set flooding levels being reached. Based on 2oo3 logic, the panels are custom designed by Hima-Sella to fit a “Maximum Envelope” based on a compartmentalised design to allow some sections to work independently, whilst other sections are in maintenance or commissioning modes. In order to allow thorough proving of the design, Hima-Sella produced a custom test rig with some actual plant level sensors connected to the inputs, testing all paths through the logic.
