System Objective

At present, dispatchers analyze the power transmission from change of operation modes always by their own experiences, so currency of the result cannot be proved. Also, because these works depend on recognize of dispatcher to electrical system, objective of the result cannot be proved. For this problem, we developed this software based on the analysis of power supply path. It reveals inherent laws of power transmission in network and provides an analyzing and assisting tool for dispatchers.

Hierarchical Partition

Along with the increasing use of cables in power grid and the increasing ration of distributed power sources’ synchronization, such as small hydropower’s synchronization, increasing the reactive power transmission on the line, make it difficult to achieve the balance of reactive hierarchical partition. Take a certain region’s power grid for actual examples, after the installation of magnetic control reactor (MCR), using immune genetic algorithm (IGA) to coordinate the capacity of magnetic control reactor and the existing reactive power resources, the results show that the magnetic control reactor does much good to absorb the system’s excessive reactive power and limit the voltage’s increasing.

To determine the inter-regional power replacement, this paper starts from the inter-regional power transmission and out-purchased demands and puts forward the analysis models of power transmission and out-purchased. Then it focuses on the decision problem of inter-regional power transmission and out-purchased where power supply exceeds power demand and provide the corresponding optimization algorithm. The models shows that inter-regional power replacement can reduce the generation pollutants emission, promote the power efficiency, and raise renewable energy grid-connected content like hydropower, wind power and so on, making magnificent economy and environmental effects.

Abstract This article solves the problem of a quantitative assessment of the occurrence of destruction in the intersystem interactions of the transport system and the electrical system of the seaport, in the conditions of the technological process in the seaport, which indicates its significant impact on the electrical system, as a result of which the reliability of the berthing power line is significantly reduced. The intersystem interactions that occur during the implementation of the technological process, as experience shows, are the causes of critical situations that occur at the border of areas of different physical nature, and the consequences are recorded, in the case under consideration, in the electrical system. A mathematical model describing intersystem destruction in quantitative form is presented in this paper using a logical-probabilistic model that reflects internal and external relationships. In the object under study, the destructive cause (collision) and the consequence (accumulation of electrical damage in the insulation of the cable line) are in the same object (the mooring power supply unit), and this is limited to the effects of intersystem destruction. In such a statement, the object of power supply of the technological process and equipment is considered as a composite object containing a cable line and an electric contact column. The problem being formulated is an important and relevant scientific task, which includes not only the question of identifying the causes of increased electrical wear of the power line, but also the development of methods for obtaining quantitative results, and in practical terms also involves the diagnosis of the technical condition of electrical equipment and timely preventive maintenance.
