development
on
regional

is introduced
?/p>
The description of topology structure of power grid is
simplified
?/p>
the

is
described
based
on
idea
of
classification and lamination
?/p>
and the inference machine is researched
based on the topology structure of power grid and operation rule
?/p>
The
operation
is
checked
by
flow

来看?/p>
这些系统在很大程度上提高了电网调度自
动化水平?/p>
减轻了调度人员的工作压力?/p>
但是?/p>
这些开票系统大多只考虑了设?/p>
电气连接关系的约束,
而没有考虑电网的静态安全约束,
对于出票的安全可行?/p>
还主要依靠调度员的主观经验来判断?/p>
j
。在这情况下,随着电网规模的不断扩
大,
电网结构日益复杂?/p>
系统的运行方式变化多端,
操作某一设备时有可能导致
其它设备过载?/p>
甚至有可能对电力系统的安全稳定性产生威胁?/p>
由此可见?/p>
