灌区污水灌溉补偿效益初探

我国水资源紧缺,城市生活和工业大量挤占农业用水并产生大量污水,致使农业清水灌溉用水危机加重。在这种情况下,我国的污水灌溉面积随着城市化加快和工业发展而迅速扩大。为了研究灌区污水灌溉相关各方效益变化,通过把灌区污水灌溉运行与梯级库群中龙头水库运行相比较,分析结果表明灌区污水灌溉存在补偿效益。文章给出了灌区污水灌溉补偿效益的概念和内涵。接着,进一步指出灌区污灌补偿效益相关研究内容,包括灌区污灌补偿相关对象分析、相关对象的效益变化研究和灌区多水源污灌补偿调度研究,并对它们进行了定性分析。最后指出下一步灌区污灌补偿研究任务和方向。     

AUTOMATIC CONTINGENCY SELECTION AND RANKING USING AN UNIFIED MODEL AND ALGORITHM FOR P - AND Q - SUBPROBLEM

A new approach of the automatic contingency selection and ranking with the network flow programming (NFP) is presented in this paper. NFP is adaptable to change the network topology as the transmission or generation branches arc in single or multiple outage. Thus the fast calculation of the contingency states by NFP cm provide the urgent information in real time N- 1 security analysis. In the paper, automatic contingency selection and ranking forP- and Q-type subproblem arc solved by an unified network flow model and algorithm. It is based on the existence of weak coupling between real and reactive quantities in power systems. The performance indices to assess the severity of contingencies are defined as the total real and reactive load required to be curtailed. The proposed ACS technique including the model and its algorithm are examined with IEEE 5-, 14-, 30-, 57- and 118- bus test systems on M-340. And the encouraging results are given in the paper.     

论劳务派遣中劳动报酬的支付

劳务派遣劳动关系较为复杂,对派遣工劳动报酬的支付,立法规定的较为混乱,需要加以明确。在支付主体方面,应明确派遣单位与要派单位皆为支付主体,但承担不同的支付责任。在支付标准方面,应规定劳动者参与协商劳动报酬的权利,并以劳动者利益为基础确定支付标准。在支付方式方面,应对扣减劳动报酬的问题作出周全规定,并在一定条件下允许要派单位直接向派遣工发放劳动报酬。     

APPLICATION OF OUT-OF-KILTER ALGORITHM TO ECONOMIC DISPATCH WITH SECURITY

This paper reports on the application of "Out-of-Kilter Algorithm" (OKA) to the real power economic dispatch with security constraints. The network flow programming is characterized by simple manipulation, fast and reliable convergence, while the OKA can treat nonzero lower bounds and may initiate with any set of flows (including infeasible flow) which satisfies Conservation of flow. The major procedure and numerical example of OKA are given in this paper. The calculating results for economic dispatch on test systems have shown that the method is feasible and effective.     

基于移动Agent的水电站分布式故

目前的分布式故障诊断主要采用C/S 计算模型，这些计算模型本身都存在一定的局限性，其中最明显的就是要求所有参与计算的节点在进行交互时，都必须同时在网络中存在。本文分析了Agent和移动Agent的特点，提出了基于移动Agent的分布式故障诊断专家系统，对其系统结构、实现方法、Agent的管理以及状态变迁进行详细的阐述。
