In "ODU of the Urals" and Tyumen RDU digital monitoring systems of stocks of stability are implemented

On June 6, 2019 JSC SO UES reported that in its branches "Interconnected Dispatching Office of Power Supply System of the Urals" (ODU of the Urals) and "Regional dispatching office of the Energy System of the Tyumen region, Khanty-Mansi Autonomous Okrug and the Yamalo-Nenets Autonomous Area" (the Tyumen RDU) the digital monitoring systems of stocks of stability (MSSS) are put into commercial operation.

SMZU is the developed JSC STC of EEC together with JSC SO UES the software and hardware complex bringing settlement process of the are most admissible overflows (AMAO) in the electric network to essentially other level. A system is intended for calculation of value TIR in real time that allows to consider the current changes of a circuit and regime situation in power supply system and by that provides additional opportunities for use of capacity of the electric network and the choice of the optimal control algorithm with the modes of power supply system without decrease in level of its reliability.

Implementation of SMZU is a real step to digitalization of power, along with such projects as input of centralized systems of antiabnormal automatic equipment of third generation in the integrated power systems and the systems of remote control of the equipment of power objects. Use in power industry of digital technologies allows to gain considerable positive effect due to creation on their base of more effective management models technology and business processes. In particular, ensuring the maximum use of capacity of the trunk power transmission lines due to application of SMZU gives additional opportunities of optimization of loading of the generating capacities in power supply system.

At the first stage the SMZU software and hardware complexes put into operation will calculate the maximum allowed overflow for four controlled sections: "APNU Kalino" and Malachite in Unified Energy System of the Urals and "CUC of the Urals – power supply system of the Tyumen region" and North – in the Tyumen power supply system. Further to this system it is going to connect also other controlled sections.

Within implementation of the SMZU software and hardware complexes in branches of System operator of ODU of the Urals and the Tyumen RDU the server hardware, the system and technology software is installed and configured, instructive documentation is developed and training of dispatching personnel in application of SMZU at management of an operation mode of Unified Energy System of the Urals and the Tyumen power supply system is provided.

In the course of preparation for input in commercial operation of digital monitoring systems of stocks of stability specialists of ODU of the Urals and the Tyumen RDU together with developers – JSC STC of EEC – participated in testing of operation of the server hardware and the software of the SMZU complexes, updated design models of power supply systems and the database on parameters of devices of antiabnormal automatic equipment for correct determination of TIR in controlled sections.

As a result of the done work the dispatching personnel received the tool allowing to estimate an operation mode of power supply system in real time. Management of an operation mode of CUC of the Urals and power supply system of the Tyumen region, Khanty-Mansi and Yamal-Nenets autonomous areas using results of calculation of SMZU allows to increase reliability of work of UES of Russia and power supply of consumers of electrical energy.
