【正文】 tage generatrix the system key position to be extremely important. By above may know, microputer protective device may enhance the protection performance and the reliability greatly, this is the microputer protection development inevitable trend. protections, control, survey, data munication integrations In realization relay protection puterizing with under the condition, the protective device is in fact a high performance, the multipurpose puter, is in an entire electrical power system puter work intelligent terminal. It may gain the electrical power system movement and breakdown any information and the data from the , also may protect the part which obtains it any information and the data transfer for the work control center or no matter what a terminal. Therefore, each microputer protective device not only may complete the relay protection function, moreover in does not have in the breakdown normal operation situation also to be possible to plete the survey, the control, the data munication function, that is realization protection, control, survey, data munication integration. At present, in order to survey, the protection and the control need, outdoor transformer substation all equipment, like the transformer, the line and so on the secondary voltage, the electric current all must use the control cable to direct to . Lays the massive control cable not only must massively invest, moreover makes the secondary circuit to be extremely plex. But if the above protection, the control, the survey, the data munication integration puter installation, will install in outdoor transformer substation by the protection device nearby, by the protection device voltage, the amperage is changed into after this installment internal circulation the digital quantity, will deliver through the puter work, then might avoid the massive control cable. If takes the work with the optical fiber the transmission medium, but also may avoid the electronmagetic interference. Now the photoelectric current mutual inductor (ota) and the photovoltage mutual inductor (otv) in the research trial stage, future inevitably obtained the application in the electrical power system. In uses ota and in the otv situation, the protective device should place is apart from ota and the otv recent place, that is should place by the protection device nearby. Ota and the otv light signal inputs after this integration installment in and transforms the electrical signal, on the one hand serves as the protection the putation judgment。 On the other hand took the survey quantity, delivers through the work. May to deliver from through the work by the protection device operation control mand this integrated installment, carries out the circuit breaker operation from this the integrated installment. In 1992 the Tianjin University proposed the protection, the control, the survey, the correspondence integration question, and has developed take the tms320c25 digital signal processor (dsp) as a foundation protection, the control, the survey, the data munication integration installment. intellectualizations In recent years, the artificial intelligence technology like nerve work, the geic algorithms, the evolution plan, the fuzzy logic and so on all obtained the application in electrical power system each domain, also started in the relay protection domain application researc 10 h. The nerve work is one nonlinear mapping method, very many lists the plex nonlinear problem with difficulty which the equation or solves with difficulty, the application nerve work side principle may be easily solved. For example exhibits in the situation in the transmission line two sides systems electric potential angle to occur after the transition resistance shortcircuits is a nonlinear problem, very difficult correctly to make the breakdown position from the protection the distinction, thus creates moves by mistake or resists to move。 If thinks after the work method, passes through the massive breakdowns sample training, so long as the sample centralism has fully considered each kind of situation, then in breaksdown time any all may correctly distinguish. Other like geic algorithms, the evolution plan and so on also all have its unique solution plex question the ability. May cause the solution speed these artificial intelligence method suitable unions to be quicker. The Tianjin University carries on the nerve work type relay protection from 1996 the research, has yielded the preliminary result ]. May foresee, the artificial intelligence technology must be able to obtain the application in the relay protection domain, by solves the problem which solves with difficulty with the conventional method. 3 Conclution Since the founding of China39。s electric power system protection technology has undergone four times. With the rapid development of power systems and puter technology, munications technology, relay technology faces the further development of the trend. Domestic and international trends in the development of protection technologies: puterization, working, protection, control, measurement, data munications integration and artificial intelligence, which made protection workers difficult task, but also opened up the activities of vast.
