2×600MW空冷亚临界发电机组辅机节能改造分析及能耗计算

Auxiliary Energy Saving Analysis and Energy Consumption Calculation of 2×600MW Air-cooled Subcritical Generators

通过对机组现有主辅机设备及高压动力系统的生产工艺、自动化控制现状等的详细分析,对机组的一次系统和控制系统采用高压变频节能改造的系统架构方案进行了优化论证。在此基础上,对该系统的关键环节做了耗能计算和投资回报分析。

Based on the detailed analysis for the production process and automation control status of existing main and auxiliary e- quipment unit and the high voltage power system, the paper makes an optimized argument for the system architecture solutions of high voltage inverter energy saving used by system of units and control system. Then, it analyzes the energy consumption calculation and return on investment of the key part in system.
