“…The conducted studies devoted to the low-voltage electrical networks operating modes [11][12][13][14][15][16][17][18] have established that the most effective balancing means the 038 kV network operating mode is the special balancing devices use with zero-sequence currents minimal resistance. This device type is used mainly in electrical networks that electricity suppliers the utility load consumers (urban and rural).…”

The article considers the using intelligent controls possibility in low-voltage rural electric networks to minimize the unbalance modes consequences. The proposed technology includes the digital data transmission compilation on the electrical energy parameters with a new balancing technical means the electrical network operating mode. Digital feedback is provided for changes the balancing device (BD) parameters by the unbalancing power consumption changing level. Based on the developed methods compilation, software for calculating unbalancing modes has been created, which makes it possible to assess the currents and voltages unbalancing effect on the power quality and its additional losses change. The “green” technology proposed version, which increases the economic and the electric energy environmental safety use in the rural electric power industry, contains a new constructive solution for the balancing device implementation. The proposed technology was tested on the measurement data basis in existing electrical networks. Based on the MALAB technologies use, changes studied indicators visualization in the before and after BD integration in the electrical network was carried out and its analysis was makes. Used on the “neural networks” MALAB technology, a preventive assessment of the unbalancing power consumption events development in the investigated operating electrical network is presented, as well as the proposed technology effectiveness assessment was carried out.

This article describes the features of voltage regulation in electrical networks of 35, 110, 220 kV. The structural diagram of the 35/10/0.4 kV network is presented. The paper also describes the adaptive automatic voltage regulation system which allows regulating the voltage taking into account the actual voltage values at the consumers’ inputs. The structural diagram of the adaptive automatic voltage regulation system in the 0.4 kV electrical network using a boost transformer as an additional means of voltage regulation is given. The system is based on voltage sensors installed in different parts of an eletcrical network sending information on voltage values to to the processing unit which generates a signal for voltage regulating supplied to the executive device and the working body whuch, in turn, change the on-load tap-changer position of a transformer. The paper justifies the need for the enhancement of the adaptive automatic voltage regulation system for different voltage classes wich allows controlling a voltage change at different power supply system levels and regulating voltage level in accordance with this change. For this problem the multi-level adaptive automatic voltage regulation systemis proposed. The system allows regulating the voltage not only in the 0.4 kV network but also in networks of higher voltage classes. The proposed system can be integrated into the structure of intelligent electrical networks.

“…The paper [14] focuses on introducing the coordinated voltage control technique for solving a voltage quality problem. Also, there is a large number of already developed means for increasing PSR and PQ, for example, systems for regulating electrical power quality parameters (for example, adaptive automatic voltage regulation [15]), transformer substation automation systems (Automatic Transfer Switches (ATS), automatic circuit reclosers (ACR) [16], under-frequency load shedding (UFLS), buses' load balancing [17]), systems of automatic regulation (compensation) of reactive power [18], [19]. At the same time, the implementation of these means as well as using methods for increasing PSR and PQ, including ones mentioned above, requires monitoring the electrical network parameters in order to accurately and quickly respond to any changes in a power supply system [20].…”
