Automatic filter compensating device
Automatic filter compensating device is intended for automatic correction of electric power qualitative indices according to GOST 13109-97. There are seven such indices. For the good performance of power consuming equipment in oil and gas sector the following indices are important:
- δUt
- Pt
- K2U
- K0U
- KU.
The automatic filter compensating device monitors the values of these indices and adjusts them to the GOST requirements. Thus, there is no voltage drop in the network segment (let us code-name it "k" segment), calculated by the formula:
- ΔUk = (PkRk + QkXk) / Uном
Application
In case of power supply from independent sources (our generating systems), a voltage drop of even a very small duration causes an electromagnetic field dropout in generators and drilling process shutdown. Therefore, using an automatic filter compensating device in a power system is a reliable protection from failures in drilling and oil production process.
