Abstract
In this article, the authors discuss the use of FACTS devices in coal mine power systems. The problems of reactive power compensation and the disadvantages of regulatory and technical documentation regarding the use of modern reactive power compensation devices are considered. The main types of FACTS devices that can be used in coal mines are identified. The scientific publications in the field of application of FACTS devices in power supply systems of industrial enterprises are analyzed. The cost indicators of FACTS devices are considered and conclusions are drawn on the theoretical technical and economic efficiency of using FACTS devices in mine conditions.
Highlights
Since the beginning of the XXI century, there has been a transition to technological structures “longwall face - mine” with an increase in power supply and the level of voltage of electrical equipment in coal mine extraction areas
Among the features of power supply systems in coal mine extraction areas, it is worth noting the lack of reactive power compensators (RPC) in the underground part of the power supply system [1], which was previously associated with the absence of explosion-proof RPC
The above devices have a high speed compared to UKRV, which is especially important for coal mine extraction areas which are characterized by a sharply variable nature of the electrical load
Summary
Since the beginning of the XXI century, there has been a transition to technological structures “longwall face - mine” with an increase in power supply and the level of voltage of electrical equipment in coal mine extraction areas. Balobanov [5], it is advisable to use devices like APF (active power filter), PF (power filter), SVC (static var compensator) in coal mines PSS The reason for this solution is that in coalmine power supply systems, it is possible to observe strong fluctuations in reactive power, harmonic distortion, and flicker. Passive devices for limiting electromagnetic interference have many disadvantages, for example, stepwise regulation, the difficulty of choosing parameters in a changing network configuration, the risk of resonance phenomena, large dimensions, etc This has led to the need for active power quality management devices based on FACTS. When placing FACTS and CPD devices in coal mine power supply systems at underground distribution points in cramped conditions, these devices are required to be compact and explosion-proof.
