In this paper the problem of finding optimal topological configurations of a power transmission system is considered with the aim of maximizing the renewable energy injection. A realistic modeling strategy for bus couplers in multiple-busbar stations is proposed. The solution of the resulting mixed-integer nonlinear programming problem (MINLP) is carried out by a novel binary variant of the Particle...
A complete secondary system can be split concerning the engineering responsibility into different parts. Example is separate engineering of line operation interlocking between substations. This paper presents a new approach to line operation IEDs engineering with exchanged information between substations, which is compatible with IEC 61850. In this paper, Architecture of Line Operation between substations...
This paper describes the benefits and techniques for performing maintenance on the electrical and mechanical interlocks in medium-voltage (MV) motor starters. These interlocks are safety features built into MV motor starters to prevent the isolation switch from being operated while the motor is running, which could result in a serious injury because the isolation switch is not rated to operate under...
Configuration complexity is a novel research field.The concept of configuration complexity is outlined in this paper, as well as current research is introduced briefly. Based on the current study results and best practice, improved configuration complexity quantitative model is proposed in the paper. Then, after an enterprise network environment is constructed in the laboratory, the quantitative model...
Network operation complexity model is proposed in this paper. This model includes nested system model, operation process model and quantitative indicator model. Then, a normalization treatment method of indicator data is put forward. After constructing a network system in the laboratory, we apply the model to the operation process of network and obtain complexity indicator value through measuring...
This standard establishes ratings and requirements for planning, design, testing, installation and operation of gas-insulated substations for alternating current applications. Typical installations are assemblies of specialized devices such as circuit breakers, switches, bushings, bus, and instrumentation. The standard is split into four sections: an introduction giving references and definitions;...
