增加电厂用户后次高压管网的调度方案

Dispatching Scheme of Sub-high Pressure Pipe Network after Addition of Power Plant

结合工程实际,为实现对新增电厂用户的供气,对LNG气化站供气和现有天然气次高压管网供气的方案进行分析,选取现有天然气次高压管网供气方案。分析比较了增加电厂用户后次高压管网的调度方案,确定采用通过流量遥调系统合理分配门站流量、利用管道储气进行小时调峰的调度方案。

In order to realize gas supply to additional power plant consumer, the schemes of gas supply from LNG vaporizing station and existing natural gas sub-high pressure pipe network are analyzed with the engineering practice. The scheme for gas supply from existing natural gas sub-high pressure pipe network is selected. The dispatching schemes of sub-high pressure pipe network after addition of power plant consumer are analyzed and compared. It is determined that the dispatching schemes of reasonable distribution of gate station flow by remote flow regulating system and hourly peak shaving by pipeline gas storage are used.
