The article deals with the tasks of ensuring the required quality of electricity in modern power systems of industrial enterprises.
The main tasks of designing and operating modern power supply systems for industrial enterprises are in addition to the rational choice of elements of power supply systems, it is also to ensure the required quality of electricity at the terminals of the power receivers. Ensuring the required quality of electricity is generally associated with the electromagnetic compatibility of the supplynetwork. The intensification of production processes is associated with the improvement of technological processes and the introduction of advanced technologies, with the use of high-performance equipment, in particular, valve converters, welding plants, powerful metalworking machines are being introduced. They are currently controlled using digital technology, these devices strictly impose high demands on the quality of electrical energy.In connection with the requirements of the quality of electricity, in the Russian Federation every 10-15 years new standards are developed, where the indicators of the quality of electric energy are normalized
