Numerical Computation of High-Voltage Field by Charge Simulation Method
Published in Sivaji Chakravorti, Electric Field Analysis, 2017
Insulated cables are used extensively for transmission and distribution of electrical power. Termination is the way in which the end of a cable is finished, so that the cable matches a power supply or another device/equipment. Such cable terminations are subjected to considerable electrical stresses during operation. A proper design of cable termination is essential in reducing the electric field distribution in and around cable termination. Figure 16.20 shows the conventional CSM simulation of a traditional single-core fluid-filled outdoor cable termination. Contrary to electric field computation within a cable, cable termination being of finite length needs to be analyzed as an axi-symmetric case study. Typically, such a cable termination comprises cylindrical cable core at live potential, earthed unit known as the deflector with semi-conducting covering, cable core insulation (e.g. cross-linked polyethylene or XLPE), insulating stress cone (e.g. silicone rubber) and the outer insulating cover (e.g. porcelain). The space within the outer insulating cover is filled with an insulating fluid. In Figure 16.20, the outer porcelain covering is taken to be cylindrical in shape for simplicity. It may be noted here that the shape of the outer covering plays insignificant role in determining the field stresses at the critical zones within the cable termination.

Thin coaxial systems can easily be terminated by special BNC connectors which have the termination network built into them. This termination is necessary to ensure that the data transmitted down the cable is not distorted by signal reflections and other similar problems.

Using Gr as input, in Line 7 of Algorithm 1 we construct the set of boundary nodes in steps and construct Ga by calculating the K () shortest-path between every pair of boundary nodes for each vehicle. This can be done in steps using Yen’s algorithm (Yen, 1971) and Fibonacci heaps (Fredman and Tarjan, 1987). In practice, we calculate paths between boundary nodes only for those vehicles that have used such nodes. Proposition 6 describes a filtering process that avoids adding unnecessary paths to Ga, reducing the number of decision variables in the problem solved in Line 8 of Algorithm 1. We use the function to denote the total travel and minimum wait time along path Proposition 7 proves the finite termination and correctness of Algorithm 1.
A game approach to the parametric control of real-time systems

In future work, we plan to implement the algorithm and for this we will focus on different restrictions on the use of parameters to ensure the decidability of the control problems and the termination of the synthesis procedures. In particular, since, in practice, the timing features of systems are given as integers, we will apply the bounded integer approach of Jovanović, Lime, and Roux (2013) and Jovanović et al. (2015). Moreover, to avoid an explicit enumeration of all the possible values of parameters, we will implement a modification of the symbolic computation of S* that preserves the integer parameter valuations which will be given as symbolic constraints between parameters.

To evaluate the key properties correctness, completeness, and termination, we rely on mathematical proofs. To conduct this evaluation in a systematic manner, each part of our proposed approach for addressing a particular feasible atomic change is evaluated with respect to these three properties. In the following, we give an overview over the essential points that substantiate our argumentation.
