摘要

辽宁电网供热季节电网调峰压力巨大

在保证供热质量的前提下尽可能降低供热机组电负荷

并合理安排电量计划

可最大限度地消纳风电。文中基于供热机组“以热定电”在线监测系统

提出了能量平衡法。通过对进出汽轮机的能量进行平衡计算

确定不同采暖抽汽热量和工业抽汽热量下机组发电量的关系

可以准确计算出一段时间内机组在给定的采暖抽汽热量和工业抽汽热量下的最大电量和最小电量范围。通过实际应用验证了该方法的准确性和实用性。

Abstract

Given the huge pressure on peak regulation of Liaoning power grid in the heating season

the methods of reducing the heating unit electric load as far as possible on the premise of guaranteeing the quality of heating

and rationally arranging the electricity plan

can achieve maximum wind power accommodation. Based on the on-line monitoring system of ordering power by heat of heating units

an energy balance method is put forward. Through the balance calculation of the energy entering or exhausted from the steam turbine

and the determination of the unit power generation relationship with different heating and industrial extraction steam quantities of heat

the maximum and minimum power generation can be accurately calculated with a given heating and industrial extraction steam quantity of heat. The accuracy and practicality of the model of ordering power by heat is verified through practical application.
