Abstract: As a measure of demand-side management, efficiency power plant (EPP) can save energy and bring economic and environmental benefits to the power system, although the widely used EPP technology may have negative effect on both power system stability and operation costs. The concept of EPP and its related characteristics such as capacity, output curve, and cost were introduced, and a probabilistic production simulation model based on the equivalent energy function (EEF) method was established to analysis the impact and benefits of EPP. With a numerical example, a result is found that EPP can not only improve the reliability and load rate of power system, thus reducing the social costs of power outage, but also reduce the total production and operating costs of power system.

Abstract: The technology of real-time fault diagnosis for nuclear power plants (NPP) has great significance to improve the safety and economy of reactor. Nuclear power plants are complex system, which collect and monitor the vast parameters. A parameter reduction method based on fuzzy rough sets was proposed. According to the characteristics the parameters were fuzzed, and they were reducted using the algorithm of forward greedy search. The decision tree was applied to learn from training samples which were the typical faults of nuclear power plant, i.e., loss of coolant accident (LOCA), feed water pipe rupture, steam generator tube rupture (SGTR), main steam pipe rupture, and diagnose by using the acquired knowledge. The result shows that this method can diagnose the faults of the NPP rapidly and accurately.

Abstract: In order to satisfy the need of automatic decision-making while shipboard-gun oppressive fire to the shore, This paper research the problem of shipboard-gun temporal fire distribution .This paper put forward the elements of oppressive fire distribution and solve out the calculation of every oppressive fire distribution elements(such as quick-firing’s quantity, surveillance firing’s quantity, every quick-firing’s ammunition wastage, every surveillance firing’s ammunition wastage and firing occasion). It could provide technical support for the realization of automatic decision-making while shipboard-gun suppression firing anti-shore.

Abstract: As operational capability of the weapon system can be varied with each fire, it proposes operational capability evaluation method for the weapon system, afterwards it proposes operational capability evaluation method for the weapon fire taking the impact indicators such as single target detection probability of shipborne early-warning radar into account.

This paper simulation training, introduces the construction of project, establishes the System architecture, and designs the idea which is used in distributed equipment support simulation training system based on the concepts、methods and principles of HLA.

Abstract: Aimed at the problem that it is hard to detect near space hypersonic target for conventional radar because of its high flight speed, flight height, and flight distance and so on, the detection performance of space-based radar to near space hypersonic target was analyzed. The characteristics of near space hypersonic target and the advantages of space-based radar was introducted, and then, the detection performances of space-based radar to near space hypersonic target from detection range, searching and tracking mode were studied. It has certain guiding significance for space-based radar development and perfection of near space detection system.

Abstract: The study of cooperative fighting between jammer and fighter aircraft is helpful to improve the ability of penetration attack. Firstly, the conception of path point threat assessment is given, based on the jamming troop model. Secondly, the jammer free fly region conception, relative theorem and the resolving strategy are given, and as a result, the dynamic searching space can be got. Thirdly, by improving Sparse A* Search (SAS) algorithm and applying it in cooperative path planning of jammer formation, the realizing process is designed. At last, simulation is made. The results show that the strategy can quickly get the best cooperative path of jammer formation whatever fighter aircraft’s penetration attack task.

Abstract: This paper presents an application of a new adaptive filtering algorithm based on a standard earth ellipsoid model in tracking ballistic missile in free flight phase. The traditional Extended Kalman Filtering algorithm (EKF) has defect in two aspects: 1) observation values applied in observation equation mainly include azimuth, pitch angle and radial distance (or radial velocity), without Doppler frequency; 2) Jacobi matrix of the system needs to be calculated, and high nonlinearization could result in degradation of calculation precision. In this paper, an algorithm used for tracking ballistic missile in free flight phase which is based on UKF observation equation with Doppler frequency is presented. The algorithm has been applied in hybrid coordinate system of the standard earth ellipsoid model (the earth is assumed as an ellipsoid planet). It has higher tracking precision compared with EKF algorithm. Monte Carlo simulation conducted to model ballistic missile in free flight phase by using MATLAB software justified the efficacy and the reasonableness of the new algorithm.
