However, due to the phenomenon of electromagnetic induction, there is a huge energy loss on the overhead ground wires. In order to find a way to reduce the energy loss, or study the possibility of tapping off power from overhead ground wires, we studied in detail the law of electromagnetic induction phenomenon on overhead ground wires. This paper focused on the main single-circuit transmission lines with two overhead ground wires, especially the 500kV cup type tower and the 330kV cat-head type tower; the ground wires are grounded at every tower. Firstly, we built the equivalent circuit diagram of the transmission lines, and theoretically calculated the parameters of the components in the circuit diagram. Then, the electric field and magnetic field at the position of the overhead ground wire were numerically simulated in MATLAB, and an equal scale reduced model was built in COMSOL Multiphysics for finite element simulation, which more intuitively showed the distribution of the electromagnetic field around the transmission lines, the simulation results showed the induced voltage phase difference on two ground wires of cup type tower is more than 160° and the induced voltage phase difference on two ground wires of cat-head type tower is about 60°. The simulation also found the induced current will decrease slowly when the shielding angle increases from 0° to 15°. Finally, a transmission line simulation experimental device was built in the laboratory for verification and some conclusions were given in the end.","PeriodicalId":62545,"journal":{"name":"电工电能新技术","volume":"33 1","pages":"36-40"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89219583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the lightning protection measures of 10kV distribution lines in the region, the composite lightning protection measures such as adding overhead lightning conductor, adding multi-chamber lightning arrester, and repairing grounding grid resistance are proposed to improve. The working principle and improvement effect of each measure are expounded. After implementing various measures, the lightning conditions and tripping data of a quarter are analyzed and compared.

The driver simultaneously realizes the decoupling of hardware and software and has high reusability.

The proposed scheme consists of two control layers to enhance energy management performance. An active-reactive optimal power flow model is formulated in the upper layer to coordinate DGs’ curtailment rate and power injection from grid-tied MGs. Moreover, an energy management model is developed in the lower layer, which schedules the power generation in grid-tied MGs. The lower layer model also determines the adjustable range for the power injection from grid-tied MGs. The adjustable range is set as complementary constraints in the upper layer model. Comparative case studies were performed on a modified 11 nodes distribution system to validate the advantages of the proposed scheme. Compared to the traditional energy management scheme in which active and reactive power from DGs and MGs are not fully leveraged, the proposed method improves the distribution network’s power quality. It also significantly reduces the active power loss and renewable generation curtailment cost in the distribution network and the fuel cost in grid-tied MGs.","PeriodicalId":62545,"journal":{"name":"电工电能新技术","volume":"16 1","pages":"93-98"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81862716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this case, there was a situation where electric power could not be supplied to the measurement system, such as an accident at the No. 1 nuclear power plant in Fukushima, Japan. With simulation code to cope with this situation, we have prepared a new alternative method of loosely coupled coils to supply wireless power through container walls. The transmission output of wireless power of the CB reinforced concrete test piece is supplied as the input of the 4 ~ 20mA equivalent circuit model, and this circuit is a cord connection method that can be configured with RLC passive elements. The special function of the code used in this model is to apply an input reference pulse to obtain the temperature response characteristics of the circuit passive elements according to the range of ambient temperature conditions. At this time, the temperature response characteristic applies a reference pulse signal to the input to analyze the abnormal signal pattern of the output change amount according to the temperature changing range in the NPP accident condition. In this case, the results of the transmitted efficiency calculation get in the range of about ~ 1% by WPT. At that time, a pulse parameter output with a temperature sweep range of 27 °C to 750 °C can be applied with the R-C passive element in the equivalent circuit model.","PeriodicalId":62545,"journal":{"name":"电工电能新技术","volume":"7 1","pages":"51-55"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85145410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
