This paper presents a study on effects of flammation retardant in polycarbonate (PC) on the luminescence phenomena during the tracking tests. A photo multiplier tube was employed to measure the light intensity, which is found to be well in accordance with the development of tracking failure. The results obtained reveals that light is easily emitted when the phase angle of applied voltage is around 90deg and 270deg. Weak initial light indicates the coming scintillation discharge; the continuously enhanced light is associated the scintillation discharge and the arc discharge. Each light pulse is composed of a main pulse and scores of small pulses. With the increasing flame retardant in PC, the luminescence intensity significantly decreases. The detecting technique of luminescence is sensitive to measure the light information from faint discharge pulses during the tracking tests.

International Symposium on Electrical Insulating Materials

Polyethylene (PE) was employed as test sample which was previously irradiated in air up to 100 kGy and then up to 1000 kGy with dose rate of 10 kGy / h by using a 60 Co gamma-source. The sample surface was corona charged by applying a series of dc stresses on needle electrode which was set 6 mm above the surface. An electrostatic probe was designed to measure the surface charge density immediately after the charging process. Obtained results show dependence of total surface charge upon the applied voltage and the radiation dose. It is suggested that surface charge accumulation depends upon the density of localized surface states, which is alternated by radiation-induced degradation and cross-linking reactions of molecule structure.

Based on constructing different types of distributed generations and energy storage equipments, this paper simulated the dynamical characteristics of MicroGrid with several operating modes under peer to peer control strategy. Two cases were used to analyze the role of storage equipment in MicroGrid. If micro turbine generation with traditional synchronization generator was used in MicroGrid as the main power adjustment unit, the frequency and voltage of MicroGrid would fluctuate during MicroGrid changed from grid-connected mode to islanded mode. In case 2, where the battery was installed in MicroGrid, the oscillation of frequency and voltage could be damped efficiently, and the operating mode switch time was shorten.

As the key-ligament between the customer and the generation & transmission system, distribution system plays a very important role in ensuring the continuous power supply for customers in safety and in high reliability. Therefore, the scientific evaluation on the power supply capacity of urban distribution network is of enormous social and economical significance. To improve the insufficiency of traditional method based on the load supply capacity referring from the transmission, this paper proposes a simple and practical method to evaluate the power supply capacity of distribution network. Firstly, the basic definition of the power supply capacity based on the N-l guideline is presented, which is composed of tow parts: one is the power supply capacity of substations, and the other is the transfer capacity of network. Secondly, according to the definition stated above, general formulas about power supply capacity of substations and network transfer capacity are deduced, and the relationship between the power supply capacity of substations and the transfer capacity of network is studied, in which the optimal transfer capacity is concluded consequently. Finally, the theories are summed up and a flow chart of power supply capacity analysis is drawn up. Through application in a district of Shanghai, China, the effectiveness and the accuracy of the proposed model are demonstrated. To summary, the method proposed in this paper under the N-l guideline is a simple and practical method to evaluate the power capacity of a distribution system; besides, the conclusions about network optimal transfer capacity based on power supply capacity can provide effective references for urban distribution network planning.

A calibration method for the medium/long-term load forecasting is presented. Firstly, a calibration model is built up, based on the regular pattern that the same trend is basically shared by the peak load and the maximum temperature. Secondly, a calibration method is presented. The first step is to correct the historical annual peak load and obtain the load which has no relations with the temperature. Then, forecast the peak load of the horizontal year by traditional way, regarding the corrected load obtained above as the historical data. At last, calibrate the result of forecasting according to the maximum temperature of the horizontal year and the final result is obtained. Finally, a practical case indicated that the model and method proposed by this paper can take the affection of temperature on the peak load into account in forecasting and calibrating, resulting in higher precision of load forecasting. The method has been successfully applied in an urban distribution network planning project.

Automatic reclosure (AR) is extremely effective in improving the reliability, stability and security of the overall power system. However, the present autoreclosure operates blindly and practices employing a fixed time. In the case of permanent fault, a second shock to the system can cause irreparable damage to expensive equipments. According to characters of transient faults and permanent faults, this paper introduces the method of Bergeron line model into the field of single-phase adaptive reclosing (SPAR). Therefore, the paper proposes a novel scheme based on the calculation of Bergeron model to realize SPAR. Theoretical analysis and simulation prove that the proposed scheme of single-phase adaptive reclosing is valid with high sensitivity and reliability.

Biodegradable polymers are increasingly expected for substitute of present insulating materials in the electrical and electronic devices. However, their electrical properties are not systematically confirmed and need further investigation. In this paper, biodegradable polyethylene (BDPE) films are employed as the specimens and high density polyethylene (HDPE) films are as the reference. The breakdown endurance of BDPE film is examined using bias DC voltage under UV-irradiation environments. The images of breakdown craters are captured through applying a monocular-video-zoom microscope. Both breakdown area and box dimension of breakdown craters are obtained by an image-pattern-identification technique. The results reveal that for both BDPE and HDPE films, the breakdown voltage, breakdown area and box dimension all decrease with the increase of UV-irradiation level. Based on comparison of the results, it shows that under UV-irradiation environment, breakdown endurance of BDPE film is better than that of HDPE film.

With the broad application of silicone rubber (SIR) insulator in high-altitude regions, corona degradation is one of the inevitable electrical degradation caused by electric stress due to the organic properties of SIR. Although this phenomenon is investigated at atmospheric pressure, there is little investigation at low pressures. It is urgent to systematically investigate effects of low pressure on the corona degradation for the reliable application. Experiments were carried out in a decompression chamber and the ambient pressure was reduced by a rotary pump from the atmospheric pressure to 40 kPa. The specimens were exposed to corona discharges at low pressures for different lapse time. The surface static contact angles on the insulator were measured to reveal the hydrophobicity changes. The currents during corona discharges at different low pressures were measured to confirm the corona degradation with variation of the pressures. The results obtained showed that the intensity of corona discharge increased with reducing the ambient pressure, which accelerated the process of corona degradation.
