1      What is?

In this submodule, the calculated buffer variance values for the relevant month are listed or calculated manually.

 


2      About whom?

Since the system is parametric, it is in a structure that can be changed by the authorized or the system administrator. But basically, this section has been developed for the use of:

This submodule is used by dispatchers.

3      Main Features

List can be filtered by year and month

By selecting the gas year and month, the buffer variance values for the relevant gas day are listed.

 


Upstream and downstream fact values are taken from Scada. And, in daily fact module these values can be imported. 

While automatic daily hydraulic simulation performs, buffer variance is calculated by the system.

Buffer variance is calculated according to the formula below.


 


In addition, upstream, downstream, line pack(D-1) and, line pack(D) values can be set manually and, buffer variance can be calculated manually by pressing Save button.
