Good Agreement

An improved Charge Simulation Method (CSM) is proposed in this paper. Based on this method, the model of the overall 500kV substation is established, and then the power frequency electric field in substation at the height of the 1.5mabovethegroundis simulated and calculated. Specifically, these on 500kV switch yard in the station are simulated and analysis. The results show that the simulation results are in good agreement with the actual substation measured results, which is proved the correctness of the model and the algorithm. This paper provides an effective method for the rapid analysis of the distribution of power frequency electric field in ultra-high-voltage substation, and also can use the method to study the effects of electric field distribution factors in substation.

Extra High Voltage

The power frequency electric field of the extra high voltage network, as an index which has an important effect on the ecological environment around has been valued by the power design and operate department. Studying the factors that affect electromagnetic environment of transmission line and protective measures can provide technical basis for the design of the transmission line, and make people to recognize the electromagnetic environment of transmission lines correctly and select the rational protection measures. In this paper, firstly the physical model of overhead transmission lines was built and the electric field was calculated, then the actual electric field under 500 kV transmission line in Jiaozuo was measured using the electromagnetic analyzer PMM8053B, finally the correctness of the theory and model was verified using the MATLAB simulation software.

This paper studies the calculation model of the power frequency electric field surrounding the high voltage transmission line, and establishes the analysis model of the ball type sensor for measuring the alternating electric field. The distortion and the measurement error of the electric field caused by the sensor are discussed in the paper. For the 35KV transmission line, the paper compare the electric field (with the sensor in) with the electric field (with no sensor) by simulation, and achieve the conclusion that putting the ball type sensor into the electric field can cause the distortion, and the value of the distortion increases with the increase of the height, which leads to the increase of relative error.

In conditions of exceeding the maximum permissible levels of power frequency electric field, the staff must use personal protective equipment. Requirements for such means are regulated by the system of occupational safety standards. The goal of this work is analyzed new requirements for power frequency and induced personal protective equipment in the regulatory interstate standards GOST 12.4.172 and GOST 12.4.283. The personal protective equipment new requirements for various types of work are substantiated to electrical personnel health safety during the maintenance and operation of power grid facilities. Increasing requirements for personal protective equipment improves the staff protection at ground potential and at wire potential, including in emergency situations such as induced and step voltage.
