摘要
煤电是我国电力碳排放的主要来源,其机组碳排放指标是实施低碳规划和运行的基本依据。考虑我国燃煤电厂数据的可获得性,提出基于物料平衡的燃煤机组碳排放指标计算方法。该方法兼顾宏观统计的易操作性和技术应用的准确性,将宏观温室气体清单编制与微观规划运行指标相统一,可提高部门温室气体清单编制的精度,并为低碳电力系统在规划运行中落实减排指标提供基础数据。某电厂实际算例验证了方法的正确性和实用性,并对影响因素进行分析,进一步表明机组煤耗不决定其碳排放序位。
Coal-fired power plants are the main source of carbon emission in power sector, so the CO2 emission rate of coal-fired generation unit is the basic foundation for the implementation of low-carbon planning and scheduling. Considering the procurability of operational data of coal-fired power plants in China and based on material balance principle a method to calculate carbon emission index of coal-fired generation unit is proposed. Considering both maneuverability of macro-statistics and accuracy of technical application, the proposed calculation method makes the drafting of macroscopic greenhouse gas inventory unified with microscopic scheduling and operational index, thus the accuracy of drafting greenhouse gas inventory can be improved and basic data can be provided to low-carbon power grid for the implementation of emission reduction index during the planning and operation. The correctness and practicality of the proposed method are verified by case study of an actual coal-fired power plant, and the analysis on its influencing factors shows that the order of carbon emission intensity of coal-fired generation units is not independent on their coal consumption.
