REACTIVE POWER COMPENSATION MINIMUM LOAD TRANSFORMERS WITH A SECONDARY VOLTAGE 0.4 KV
Abstract
An original technique for determining the capacity of a permanently switched-on stage
of a capacitor plant with a rated voltage of 0.4 kV, transformers 6 (10) / 0.4 kV, is proposed to reduce
losses of active electricity in such transformers of power supply systems. It is assumed that the voltage
that is supplied to consumers is a potential form of electricity. At the same time, in the electromagnetic
field of consumers' electric receivers (as legal entities), it turns into an electrokinetic form of that kind
of energy that can perform a specific useful work. The modern mathematical model of the power supply system is conditionally-mathematical, which considers the reactive component of electricity in the
electric power system as a separate type of energy, which is transferred to consumers and determines
the volume of its consumption by the amplitude values of the load of their reactive power. Therefore,
the robot uses a real-mathematical model of electricity transmission, which allows adequate (according to the current values of such a load) to determine the negative impact of the reactive load of consumers on the energy efficiency of energy resources in the electric power industry. Based on such
physical principles, it is proved that at a voltage of 0.4 kV, the reactive load compensating devices in
idling mode of power supply system transformers are not economically feasible to use. Transformers
in this mode must be turned off. However, under the condition of a special selection of the capacity of
the mentioned capacitor installations and inductive reactors, transformers of the TM-6 (10) kV type
can be applied in the form of filter-compensating devices of electrical networks that supply consumers
with voltage 6 (10) kV.
