This process is very dynamic and subject to influencing external factors every second. Synchronization is a set of actions to turn on synchronous generators for parallel operation with other synchronously rotating generators of a power plant or an electric power system [1] . That is, the synchronization operation is an integral part of the process under consideration. Synchronization is a complex and responsible process, since during its implementation there is a danger of damage and violation to the integrity of the unit. Currently, synchronization is carried out both manually by staff and when using automatic control. However, in order to avoid the consequences of improper inclusion of the generators, when performing synchronization, the influence of the human factor should be eliminated as much as possible. To ensure the optimal operation mode of the station units, as well as change their states: start, shutdown, switching on for parallel operation, it is necessary to automate the power generation process and switch to automatic control. The synchronization operation must be semi-automatic or fully automatic. Devices for automatic synchronization process are called synchronizers.","PeriodicalId":299510,"journal":{"name":"2020 3rd International Youth Scientific and Technical Conference on Relay Protection and Automation (RPA)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127081383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The promising areas of application of the PMU are: ACS TP of the substation, distributed relay protection systems, emergency and mode automation, combined distributed control systems, protection and automation. The areas noted above include such promising and important tasks as optimization of the modes of the electric power system in terms of voltage and reactive power, adaptive relay protection. The solution to these problems requires a mathematical model of the network. Part of the model must be represented with high accuracy, and the rest of the external network can be represented using an equivalent, which has the same response to the investigated part of the system as a real external network. Using an equivalent allows you to increase the speed of calculations, simplify them and reduce the required computing power. PMU allow the formation of the equivalent of the selected part of the power system with an accuracy sufficient to implement the above tasks online, adapting to the network operating mode.An algorithm for the formation of the equivalent of the power system and the determination of its parameters according to the data of the PMU in the absence of data on the topology and parameters of the equivalent part is developedThe developed algorithm makes it possible to take into account possible interconnections in the external part of the power system, ensures the specified accuracy and high speed in the absence of information about the external power system, for the algorithm to work, it is enough to install the PMU only on the boundary branches, the selected equivalent can be relevant in a number of operating situations.","PeriodicalId":299510,"journal":{"name":"2020 3rd International Youth Scientific and Technical Conference on Relay Protection and Automation (RPA)","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115833113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The centralized emergency control system (CECS) plays an important role for solving this task, since the main target of the CECS is minimization of the emergency control volume by control actions (CA) identified in real time according to the current regime [1] . Information about the current scheme, regime and location, and, also, type, operational incident severity in the area of emergency control is collected in the central unit. Based on this information, the central unit identifies the required control actions, and then, these CA are transferred to control objects for implementation, increased accuracy of the CA and reduced redundancy of them. The mandatory component of the CECS is the state estimation (SE) module [2] .

The control system calculates optimal states of reactive power compensators and voltage regulators, without using of a common data collection point. The distributed power loss optimization is achieved by dividing of the specific grid part into energy clusters (groups of energy facilities) according to geographical, economic or other principals. Every energy cluster is represented by an agent which receives measurements within its own area (energy cluster) and is able to request measurements from adjoin to the energy cluster substations of other clusters. Based on these measurements, the agent creates equivalents of the external grid and implements local (inside one energy cluster) optimization. Every agent executes this optimization task and then a negotiation process begins. During the negotiation process an optimal for all energy clusters mode is defined.The distributed system has a three-level architecture:–The upper level. The level contains energy cluster agents, which interact to each other and determine the optimal mode for every energy cluster and for the whole part of a grid.–The middle level. The level performs collection of equipment sates within the energy cluster and sends commands to equipment, which were defined during high level optimization process.–The lower level. The level contains local regulators of substations to keep determined power mode during diurnal cycle.The upper level optimizes the operation mode of the energy cluster group by agent communication. This process is a trading process among agents, in which the reactive power compensators states and voltages at the boundary substation of energy clusters are iteratively changed to determine a mode with minimal active power losses.The middle level represents an interaction of power equipment agents. The agents collect information about the current state and send it to upper level agent. When the state of the energy cluster has been determined during optimization process, voltage setpoints for every substation are sent back. The power equipment agents receive voltage setpoint and determine states of reactive power compensators and voltage regulators to implement the setpoint.The lower level of the system is aimed to maintain determined operation mode during diurnal cycle. It contains substation regulators, which controls installed reactive power compensators and voltage regulation equipment (tap-changers).The developed system has the following advantages:–Self-configuration of the system: the applied approach allows automatically detecting topology changes and rebuilding the operation of algorithms without additional human intervention.–Easy horizontal scaling: if a new energy cluster is added to the system, all its neighbors will automatically detect this agent and take it into account for the next optimization.–The system does no","PeriodicalId":299510,"journal":{"name":"2020 3rd International Youth Scientific and Technical Conference on Relay Protection and Automation (RPA)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121637581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All this affects the decrease in the inertia of the system as a whole, therefore, the speed and nature of transients as a result of, for example, short circuits in the network is significantly changing. Thus, in the event of a power shortage due to loss of generation or loss of communication with the system, a significant decrease in the frequency is possible in very short time intervals due to the small values of the system inertia. In addition, there is an acute question for the board, operational reliability and stability of networks with distributed generation in isolated operating modes, since there is a problem of coordination of each of the inverters and their correct configuration.","PeriodicalId":299510,"journal":{"name":"2020 3rd International Youth Scientific and Technical Conference on Relay Protection and Automation (RPA)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134223369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
