This research work suggests a new method of obtaining the artificial genetic code in the system of the electric power transmission network. On the basis of the method, a new method of support is presented to examine the regularities of structural - parametric development in the electric power transmission network, which is called the method of artificial evolution. The formulation of the artificial genetic code (information code) was based on a specific equation of the matrix of the process A (of the transmission of power and electric energy) and then, the notion of the development was linked with the motion of roots. For that purpose, Evans' root lines were applied. There have also been given examples of how to use the information code in the implementation of the system development in the electric power transmission network relying on the transmitting method of the artificial evolution.

Among many unsolved issues, which meaning in the last years violently raised, there are issues of studying development of technical and technical-economical problems. There are various methods of studying patters of development, various methods of designing it and there are used different programming environment and studying methods. In present paper there have been used the theory of control and systems [2,3] and build on its base systems development engineering [12], which in relation to the system of electricity market well arrange studying problems. It also permits to execute a study about regularity of development so actual conjuncture of system of electricity market, also its final conjuncture, named in subject literature vision of system. Usage of development engineering is linked with the need of executing identification of system for gaining a system model, educe on the base of the model of artificial genetic code, generation of new genetic code new system conjuncture and to educe an information from a code which will have a structure and parameters of new system of electricity market. This paper contain also aspects of theoretical and practical reference of development engineering to electricity market understand as system in particular from a point of view of efficiency of development and a safety of development.

W przypadku badania prawidłowości rozwoju krajowego systemu elektroenergetycznego (dalej: KSE) nie jest możliwe opracowanie modelu na drodze modelowania, stąd też podjęto próbę uzyskania modelu w procesie identyfikacji przy wykorzystaniu metody arx oraz środowiska MATLAB i System Identification Toolbox. Dla założonego eksperymentu badawczego uwzględniającego jedną zmienną wyjściową oraz 14 zmiennych wejściowych uzyskano model MISO w postaci macierzy th. Model th zapisano w postaci modelu rozwoju uzależnionego od czasu długiego θ, po czym przeprowadzono interpretację jego współczynników jako podstawowych elementów macierzy th. Podano też wyniki analizy dotyczące wpływu współczynników modelu na wartość wielkości wyjściowej y1(θ) - mocy osiągalnej elektrowni (ogółem).

In the case study of regularity of development the national electricity system (KSE- NES) it is not possible to develop a model by modeling, thus/hence attempt was made to obtain a model in the identification process using the arx method, MATLAB and System Identification Toolbox. For this complex research experiment which was taking into account one output variable y1(θ) as the achievable power of power plants (total) and 14 input variables, MISO model in th matrix was obtained. Th model was saved/recorded in the form of a development model which is dependent from long time θ, then interpretation of its coefficients as the basic elements of the matrix Th was conducted. Result of the analysis on the impact of the model coefficients on the value of the output was also given, i.e. power achievable by the power plant.

W pracy przedstawiono nową metodę otrzymywania neuronowego modelu dokumentu tekstowego. Taki model może być wykorzystywany m.in. do zdalnego sterowania poszukiwaniem odkryć w sztucznym świecie dokumentów internetowych. A zatem na bazie teorii sterowania i inżynierii systemów zdefiniowano w tym względzie model elementarnego dokumentu tekstowego oraz model elementarnego systemu przetwarzania wiedzy zawartej w dokumentach tekstowych. Następnie zaproponowano neutronowy model dokumentu tekstowego oraz sieć neutronową jako schemat zastępczy modelu przetwarzania wiedzy zawartej w neuronowym modelu dokumentu tekstowego.

W przypadku badania prawidłowości rozwoju krajowego systemu elektroenergetycznego (KSE) z punktu widzenia zmian stopnia wewnętrznej organizacji systemu oraz zmian poziomu sterowania wygodnie jest otrzymać katalog modeli kroczących stacjonarnych w postaci macierzy th lub w przestrzeni stanów (ss) [1-3, 5, 13]. Modele stanowią źródło informacji do uzyskania metamodeli rozwoju oraz do zbadania zmian macierzy th czy też macierzy A, B, C i D oraz ich elementów w czasie długim θ [6, 8-11]. Prawidłowości rozwoju stanowią podstawę do sformułowania paradygmatów rozwoju systemu KSE, a nawet praw jego rozwoju [6, 8-11]. Praca jest kontynuowana w pracy pod tym samym tytułem głównym oraz podtytułem: Część 2. Komparatystyka metod identyfikacji.

In the case of testing the correctness of the development of the national power system (NPS) from the point of view of the change in the internal organization of the system and changes in the level of control it is convenient to receive a catalog of models stationary rolling in th form of a matrix or in the state space (ss) [1-3, 5, 13]. Models are a source of information to obtain meta-models to examine the growth and changes in th matrix or a matrix A, B, C and D and their components in a long time θ [6, 8-11]. Laws of development are the basis for formulation of the NPS system development paradigms, and even the rights of its development [6, 8-11]. Work continues in the work of the same title and subtitle major: Part 2 Comparative methods of identification. In this paper, the assignment is not dealt with ranges of stability, and thus include examining whether the analyzed periods is the sustainability of the development of the elements of movement, so that the development does not exceed the ordinate axis Im (s) and were maintained appropriate strengthening the relationship between the ratio and time constants. Results of this type have been presented at previous conferences CAinEE [8-11].

W pracy zaproponowano pewną nową metodę identyfikacji systemu elektroenergetycznej sieci przesyłowej prowadzącą do zapisu natury rozwoju przy pomocy tzw. kodu informacyjnego, będącego w istocie obliczem zmian parametryczno - strukturalnych systemu rozwijającego się. Metoda ta sprowadza się w gruncie rzeczy do identyfikacji potrzeb i możliwości w poszczególnych kanałach strumieni organizacyjnych, a wiec do identyfikacji tzw. rozbieżności systemowych w ujęciu teorii systemów. Do sformułowania kodu informacyjnego wykorzystuje się macierz systemową oraz równanie charakterystyczne, a w zasadzie jego pierwiastki. Z kolei możliwość związania zagadnienia rozwoju z ruchem pierwiastków równania charakterystycznego stwarza wygodny aparat do badania prawidłowości rozwoju systemów sterowania.
