The selection of the optimal 6 kV power supply scheme plays a crucial role
in ensuring the reliability, efficiency, and economic feasibility of the power
supply system. By choosing an optimal scheme, energy resources can be used
efficiently, equipment lifespan can be extended, and system reliability can be
enhanced. This approach prevents unnecessary energy losses and reduces the
likelihood of equipment failures caused by incorrect scheme selection.
The importance of an optimal power supply scheme lies in its ability to
minimize energy losses, thereby reducing production costs and improving
energy efficiency. Additionally, a well-selected scheme ensures the reliability of
the power supply system, prevents failures, reduces maintenance costs, and
guarantees the stability of production processes.
When selecting the optimal power supply scheme, it is necessary to
consider several critical factors. These include the nature of the loads and their
fluctuations, the reliability of the power supply source, and the technical
parameters of the equipment. By correctly evaluating and analyzing these
factors, the most efficient and reliable scheme can be selected. Conversely, an
incorrectly chosen scheme reduces the operational efficiency of the system,
increases the frequency of failures, and raises overall costs.
Optimal schemes simplify the management of essential parameters needed
for the stable operation of the system, reducing power supply interruptions. As a
result, production processes become more efficient and reliable.
The primary focus of this section is on the optimal method for connecting
transformer substations (TPs) to the feeder. Basic schemes are generally divided
into two types: trunk and radial (Figure 1).

Figure 1. Basic Power Supply Schemes: a) Radial, b) Trunk
Trunk Scheme:This type of scheme is organized by connecting
multiple transformer substations (TPs) to a single trunk line. The trunk scheme
is primarily used for covering long distances and allows energy transmission
from a single primary power source to multiple networks. The main advantages
of trunk schemes are as follows:
High efficiency in power delivery.
Improved supply safety and stability.
High reliability, as even if there is an interruption in one part of the trunk
line, power supply can continue through other parts.
Radial Scheme:In the radial scheme, each transformer substation (TP) is
independently supplied from its source. This scheme is mainly used for small or
medium-sized networks. The advantages of radial schemes include:
Lower construction and operational costs.
Simplicity and speed in maintenance.
Independence of each element of the scheme, making it easier to detect
and eliminate problems in the system.
In the 6 kV rural power supply, the selection of an optimal scheme involves
examining all combinations of radial and trunk schemes.
The selection of an optimal power supply scheme is conducted through three
methods:
1.
Designing;
2.
Modernization;
3.
Evaluation of existing schemes.
These three methods differ based on the type of input data. The primary
input data include the location and capacity of transformer substations (TPs). In

the design method, several potential points for TP installation are determined.
In the modernization and evaluation of existing schemes methods, the current
TP locations are already established, but in the modernization method, newly
proposed TP locations can also be introduced.
In conclusion, the methods of designing, modernization, and evaluation of
existing schemes are selected based on available data. Correctly assessing the
necessary parameters through these methods is essential for choosing the
optimal scheme and ensuring the stable operation of the system. As a result,
selecting the optimal scheme contributes to providing a power supply system
with high efficiency and reliability.
