表6.1发电项目投产边界因素敏感分析表
地区/类型负荷水平bl]l电煤总量bl2]
其中:
)l表格列方向为分区域分类型电源列;行方向为各个边界因素,包括:
负荷水平、调峰需求、地区电煤总量、主要交换线路容量等;
2)表格内容为三个情况下优化装机容量:比如x[,y习,具体含义为x为其
他边界因素不变,只对应因素降低一定标准后(比如降低负荷水平、增加电煤
总量……)的对应地区对应类型机组的装机容量,y为正常情况下的装机容量,
z为边界因素提高一定标准后的优化装机容量.
这样表格中就明确地反映出:(a)从列方向看,在哪种因素变化的情况下各
地区各类型电源优化装机容量的变化;(b)从行方向看,各地区各类型电源优
化装机容量的变化受哪些因素的影响以及影响幅度.
根据装机容量边界因素敏感分析表可得基础装机容量表,具体为:
表6.2基础装机容量表
地区/类基础装机容量表表格结构与装机容量边界因素敏感分析表一致,只是表格
内容只有一项,其数值为装机容量边界因素敏感分析表对应位置x[,y习中的最小
值,也就是说基础装机容量表中反映出各地区各类型电源优化装机容量的一个
第6章电力系统优化规划的评估体系
至少基准.
必投项目为所有因素在分析范围内变化的交集,因而可定义必投项目矩阵

界因素在合理的范围内变化对各个地区各种类型机组装机容量的影响.
6.2.2电源项目竞争能力精细评判
在上一小节中,根据系统现状、将来负荷需求以及电网扩展方案,考虑各
个边界因素的影响,将全部电源划分为必投电源、边界电源和劣势电源三大类,
下面对各大类电源项目竞争能力进行精细评判,从进一步明确各地区各类型电
源的地位,为规划决策提供充分依据.在电量竞争市场中,发电的运行成本直
接影响发电公司的报价、收益和市场份额,为此本文将发电的运行成本的高低
作为精细评判的指标.
发电运行成本主要包括两个部分:()l可变运行成本,主要为燃料成本;(2)
固定运行成本,主要为设备折旧.
可变成本部分比较直观,然而固定运行成本各种类型电源由于单机容量不
同等因素,使得不具备直接的可比性,为此需要将其折算为单位电能设备折旧,
即:()l计算总投资,包括电厂、机组、脱硫设备、接入费用等;(2)计算扣
除到计算期末的残值的有效投资值.设项目投资为P,投资回收年限为T,利用
年数=t1为计算期间内该投资项目已经发生的年数,将投资P折算为将来T年

Table 6.1 Factors power projects put into operation the border-sensitive analysis table
Region / type of load level bl] l total electricity bl2]
Of which:
) l form points out the direction for the regional classification type power supply included; the border for each direction of factors,including:
Load level of peak demand,the total areas of electricity,the main exchange line capacity,etc.;
2) forms the contents of the three cases for the optimization of capacity:for example,x [,y habits,their specific meaning for x
He borders being equal,only the factors corresponding to lower some standards (such as to reduce the load level of electricity
Total ......) corresponding to the type of the corresponding region of the installed capacity of generating units,y is the installed capacity under normal circumstances,
z to the boundary element standards to improve the optimization of a certain capacity.
This table clearly reflects:(a) from the column direction,in which case changes in the
Various types of regional changes in installed capacity of power optimization; (b) from the direction of view,the priority areas of various types of power
Of installed capacity by the change and what factors affect the rate.
The installed capacity of the border in accordance with the sensitive analysis of factors that form the basis of installed capacity of available tables,in particular:
Form the basis of installed capacity of 6.2 Table

6.2.2 Fine competitive power project evaluation
In the previous section,the status of the system,the future load demand and the transmission network expansion program,taking into account
Border factors,all power will be voted into power,and the inferior border power supply three categories,
The following types of power projects on the major competitiveness of fine judge further defined the region from various types of electric

Indicators as a fine judge.
Operating costs including power generation in two parts:() l variable operating costs,mainly fuel costs; (2)
Fixed operating costs,mainly for equipment depreciation.
Comparison of intuitive part of variable costs,fixed operating costs,however as a result of various types of power do not stand-alone capacity
The same factors that make does not have direct comparability,for which needs to be converted into units of energy equipment depreciation,
That is:() l calculation of total investment,including the power plant,unit,desulfurization equipment,access costs,etc.; (2) Calculation of deduction
