Modelling of boiler fireside control in flownex software environment

With the influx of renewable generation technology and the constraints placed on the grid due to unplanned maintenance on aging power stations, coal fired stations designed for continuous base load production have to fulfil the role of frequency support. With the high inertia of the coal fired power stations, the dynamic operating philosophy of frequency support will impact negatively on the overall efficiency and life expectancy of these plants. The solution proposed is to develop a computational model of the boiler controllers capable of optimising boiler fireside control loops and control philosophies. The model will enable engineers to test and optimize various control parameters. The model will also be a safe environment for testing transient scenarios, such as the loss of a draught group or a multiple mill trip.
