Beijing-Tianjin-Tangshan is the load center area in the North China Power Grid. The power supply in this region has a heavy reliance on external power grid, thus, there is not enough dynamic reactive support in this area and the voltage stability problems may be much more serious than the angle stability problem. In order to solve the above problems and improve the power system stability, this paper discusses a kind of control strategy for practical power grid. All the issues are studied with full scale transient simulation. The methods proposed for the mitigation of voltage instability by using Controllable HV Reactor are flexible and its coordination with other conventional measurements is convenient. Simulation results with serious faults show the effectiveness of the control method. Finally, some suggestions are given, which will make a significant contribution to the stability of power grid as well as reduce the load shedding capacity under some supposed fault conditions.","PeriodicalId":435652,"journal":{"name":"2011 International Conference on Advanced Power System Automation and Protection","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129594470","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}

Firstly, the fault section is determined on line by comparing the time difference between the arrival time of the fault induced initial travelling wave detected at two ends of the combined line with a setting value. Then, according to the different fault section, the corresponding fault location algorithms are derived. In order to test the validity of the presented fault locating scheme, a locating system is developed based on double-ended travelling wave principle for an actual combined line. In the system, one fault locator is installed at each terminal of the combined line and synchronized by a GPS based power system synchronous clock. The two fault locators can communicate with each other through a 2M multiplexing optical-fiber channel. Actual operation experience shows that the presented fault locating technique for HV combined lines based on double-ended travelling wave principle is feasible.","PeriodicalId":435652,"journal":{"name":"2011 International Conference on Advanced Power System Automation and Protection","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129459487","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}

It is required to propose a new scheme to protect the distribution system with DGs. In this paper, an adaptive protection scheme has been proposed to solve this problem. The new scheme is based on high reliability communication system, by installing a computer- based relay in the substation and dividing the distribution network into zones.
