Automated control systems in power industry

Abdullazyanov E.Yu., Sadykov M.F., Davletshin R.R. Ivanov D.A., Galieva T.G., Mochalov N.S., Vassunova Yu.Yu., Valyuk A.S.  Robotic system for energized power line equipment diagnosis and maintenance

Efficient condition control of high-voltage equipment requires its better information observability. In this context, the transfer from the diagnosis and planned maintenance of high-voltage equipment to its energized diagnosis and maintenance is the worldwide trend of the recent decade. This implies the need of remote automated robotic systems for condition diagnostics and maintenance of high-voltage power lines. The paper describes robotic systems which improve the accuracy of equipment health identification, assess its residual life and carry out minor repairs of energized power line equipment. It presents KGEU robotic system furnished with specialized sensors and tools enabling flaw detection and repairs. The solution improves power line’s reliability, decreases system average interruption duration and frequency indices (SAIDI and SAIFI), reduces power undersupply, minimizes benefit losses, and increases personnel safety.

Keywords: power line, robotic system, diagnostics, ultrashort frequencies, electromagnetic radiation, partial discharge monitoring.

Faruntsev S.D.  Multi-parameter neural controller for oil emulsion heater

The paper describes a solution for improving oil emulsion quality by upgrading field automation systems of oil treatment units at oilfields operating under intensive disturbances. It presents a neural predictive controller based on nonlinear autoregressive moving average (NARMA) models. As against the conventional single-loop NARMA-L2 controller, the new solution supports several inputs formed by disturbance and manipulated variables. The implementation algorithm is simpler than the popular model predictive control (MPC) technology that results in faster controller operation. The justification of the method is included along with the results of the synthesis of an MPC system for the PP1.6 mobile oil emulsion heater. Test results are compared with the ones for a conventional MPC.

Keywords: oil emulsion quality, disturbances, predictive control, nonlinear autoregressive moving average model, NARMA-L2 multi-parameter neural controller, mobile oil emulsion heater.
