In the past quarter, we carried out substantial work on the development of the calculation and analytical applications included in CK-11. One of the significant improvements affected the State Estimation module, designed to determine the most probable electrical regime of the power system that most accurately corresponds to a set of parameters measured at a specific point in time and satisfies the laws of electrical engineering.

As is well known, telemetry received from power facilities contains inaccuracies due to measuring instrument errors, communication channel interference, non-simultaneous measurements, and other factors. Distorted data can lead to an increased number of errors in electrical network regime analysis. The State Estimation module in CK-11 is responsible for identifying such distortions.

The updated algorithm of the State Estimation module has gained the ability to account for the influence of temporary equipment. The algorithm now takes into consideration the presence of the following changes in the electrical network:
- installed portable earthing connections
- busbar splits and installed jumpers
- connected mobile generators
- network breaks that have occurred

As a result of the implemented improvements, the system allows calculations to be performed with higher accuracy, taking into account the actual configuration of the electrical network.
