APPLICATION FOR QUALITY ANALYSIS OF BALANCING MOMENTARY POWER OF PRODUCTION AND CONSUMPTION

V tem delu je predstavljena zasnova in izdelava aplikacije za analizo kakovosti izravnave odstopanj v elektroenergetskem sistemu. Namen izdelane aplikacije je prispevek k izboljšanju kakovosti vodenja našega regulacijskega bloka SHB in njegovih regulacijskih območij Slovenije, Hrvaške ter Bosne in Hercegovine. Aplikacija je bila izdelana v okviru praktičnega usposabljanja v podjetju Eles d.o.o., ki je sistemski operater prenosnega omrežja Slovenije. Zahteva za aplikacijo je prišla s strani podjetja in je bila izdelana po projektnem načinu dela. Programiranje je bilo izvedeno v programskem okolju Visual Basic for Application, ki nam omogoča manipulacijo s programom Microsoft Excel. Rezultati so grafično in številsko ponazorjeni v programu MS Excel in nam omogočajo vpogled v kakovost vodenja regulacijskega bloka SHB in njegovih območij.This work presents planning and production of computer application for quality analysis of balancing of electric-power system. The purpose of this application is a contribution to the quality of balancing of control block of SHB and its control areas of Slovenia, Croatia and Bosnia and Herzegovina. The application was developed in period of practical education in Eles d.o.o., which is a transmission system operator of Slovenia. Request for application came from company and it was made according to project work method. Programming was done in programming enviroment Visual Basic for Aplication, which allows manipulation with program Microsoft Excel. The results are graphically and numerically illustrated in MS Excel and allow us an insight into the quality of managment of control block and its areas

Algorythm for Close-to-Real-Time Monitoring of Calculation Quality of Area- and Block Control Error

V letu 2017 je bila sprejeta nova evropska zakonodaja, ki od sistemskih operaterjev prenosnih omrežij zahteva realizacijo orodja za spremljanje kakovosti izračuna napake regulacijskega območja (ACE). Pričujoče delo opredeljuje razvoj, zasnovo in izdelavo algoritma za sprotno spremljanje kakovosti izračuna ACE. ACE predstavlja vhodni parameter sekundarnega regulatorja frekvence, ki je pri slovenskemu sistemskemu operaterju prenosnega omrežja (ELES d. o. o.) realiziran v sistemu SCADA/EMS. Namenski cilj algoritma je izboljšanje kakovosti regulacije frekvence in delovne moči v elektroenergetskem sistemu Republike Slovenije in izpolnitev zahtev evropske zakonodaje. V okviru celotnega dela je bilo raziskano zakonodajno in tehnično ozadje, ki je ključno za proces izračuna ACE. Analizirani so bili vsi vhodni podatki, za katere je predvideno, da bodo nujni pri implementaciji algoritma v sistemu SCADA/EMS. Za namen določitve ključnih lastnosti algoritma so bile izdelane statistične analize na osnovi preteklih podatkov. Na podlagi ugotovitev teoretične opredelitve problematike je bila izdelana zasnova algoritma. Skladno z zasnovo je bil izdelan testni algoritem v razvojnem programskem okolju Matlab, ki zajema vhodne podatke iz programa Microsoft Office Excel. Celotno magistrsko delo podaja izhodišče za realizacijo orodja za spremljanje kakovosti izračuna ACE v sistemu SCADA/EMS. Realizirano orodje bo odgovornemu operaterju elektroenergetskega sistema v republiškem centru vodenja Slovenije omogočilo vpogled v kakovost izračuna ACE in v stanje vseh ključnih vhodnih parametrov blizu realnemu času.In year 2017 new European legislation came into force which obligates transmission system operators to implement a tool for monitoring the quality of area control error (ACE) calculations. This work defines the development, basic scheme and programming of an algorithm for monitoring the quality of ACE calculations close to real time. ACE represents the input parameter of the secondary frequency controller, which is implemented in the SCADA/EMS system of Slovenian transmission system operator (ELES d. o. o.). The purpose of this algorithm is to improve the quality of load frequency control in the electricty power system of the Republic of Slovenia and to meet the requirements of European legislation. In the course of the whole work a legislative and technical background was considered that is relevant for the process of ACE calculation. All input data which are necessary in the implementation of the algorithm in the SCADA/EMS system were analyzed. For the purpose of determining the key characteristics of the algorithm statistical analyzes were made based on historical data. Based on the conclusions of the theoretical analysis, the basic scheme of algorithm was designed. In accordance with the scheme, a test algorithm was developed in the Matlab development environment which is using the input data from Microsoft Office Excel. The entire master thesis provides the basis for the realization of the tool for monitoring the quality of calculation of the ACE in the SCADA/EMS system. The implemented tool will enable the operator of power system in the national control centre of Slovenia to inspect the quality of the ACE calculation and the status of all key input paramters close to real time
