阐述了3×33 MV·A硅钙合金电炉1×7.5 MW余热发电系统并网接入及电网调度自动化技术的应用,这对保护电站安全和经济运行具有重要意义.1×7.5 MW余热发电机组10 kV输出通过110 kV主动力变压器升压后用于自用,并在原有110 kV电力调度自动化的基础上建成了余热发电系统远动、监控和电能采集的数据网系统,以较少的投入实现了安全、经济、节能和环保运行的目的.
The application of the grid-connecting and dispatching automation technology for the system of 1 × 7.5 MW waste heat power generation with the 3 × 33 MV · A silicon calcium furnace was described,which had important significance for safety and economic operation of the power plant.The 1 × 7.5 MW waste heat generator was output with 10 kV and then the voltage was boosted by the 110 kV main transformer for their own use.Based on the original 110 kV power dispatching automation,the data network system of telecontrol,monitoring and energy collection for the waste heat power generation system was established,which achieved the goal of the safe,economic,energy saving and environmental protection operation with less investment.
