In this paper, a new approach for detecting and identifying bad data is developed in order to improve the performance of power system static--state estimators. The implementation of computers in power system real-time control has been an important trend of modernization ever since the 60's. The static-state estimator, as a basic element in the power system real--time control, which ought to be provided with the importance of detecting and identifying function has been described. Based on the utilization of residue resources and the analysis of the property of its sensitivity matrix, the basic principle, solving method and programming technique of the estimation-identification approach have been discussed. In addition, some results of simulating test are given. Test results have shown that the performance in identifying bad data is quite well, especially successful in the case of multi-data occurance. Finally, the advantages and disadvantages of this approach have been commented, and it is expected to be a developing practical approach in real-time applications.

为了完善电力系统静态估计器的功能,本文发展了一种新的不良数据识别方法──估计识别法。 计算机实时控制是60年代以来电力系统现代化的重要趋势之一。本文概述了作为电力系统实时控制的基本环节的静态估计器所应具有的检测、识别功能的重要性,讨论了以充分利用残差信息资源和残差灵敏度矩阵的性质为基础的不良数据估计识别法的理论、方法和程序性能,并且给出了部分模拟试验结果。试验表明,这一方法具有比较完善的识别功能,特别对于处理多个不良数据,成功率很高。文章对这一方法的实时性和优缺点作了评价后,认为是很有发展前途的一种实用方法。

This is a companion paper to a paper of the same title, Part Ⅰ, in which the electric power flow problem is reformulated to account for harmonic signals which arise from nonlinear loads. In this paper, implementation and practical applications are discussed. The problem of initialization of bus voltages (including harmonics) is considered and convergence of the algorithm is assessed from the theoretical viewpoint and from the results of actual studies. The principal content of this paper is two examples both containing nonlinear loads (rectifiers).Conclusions and recommendations are made concerning the application of harmonic power flow studies. The salient recommendation is that in the presence of nonlinear loads (especially during light loading) or in systems containing HVDC lines. harmonic signals should not be ignored.

A new circuit of angle transducer is described. It is a phase-in-verted rectifying and filtering circuit consisting of a selsyn, diodes, resistors andcapacitors etc. The transducer can change angle displacement into d. c. voltage. Thereis a relationship of sine function between d. c. voltage output and angle displace-ment input in every operating intervals. The main advantage of the transducer is thatit can eliminate the null-position voltage, which exists in the form of the residuala. c. voltage output in the case of using selsyn only, therefore the precision of themeasurement can be greatly improved. Besides, the circuit structure of the transdu-cer is simple. It is easy both in implementation and regulation. It is cheap in cost.In short, it is a simple, reliable, economical and practical angle transducer. In thispaper, the output characteristic (voltage-angle characteristic) of the circuit of angletransducer is theoretically analysed in detail and is studied by experiments. Quanti-tative relationships between output characteristic and parameters of the circuit areobtained, and simple and practical formulas for design are derived. For example,output characteristic is analysed and operating intervals are divided under the load-ed and non-loaded conditions. The load effects upon the range of operating inter-vals are discussed. The problems such as regulation of the transfer coefficient and"zero", extension and reduction of range, angle and voltage displacement of outputcharacteristic are also discussed. Therefore, output characteristic curve can be moved,extended and reduced along α-axis or U-axis on Decker coordinate plane. Consequ-ently, the transducer can be made to satisfy the design specifications presented bythe users. Based on theoretical and experimental study, principles of choosing circuitcomponents are presented according to the design formulas derived and the designdemands, and a new method of determining parameters of components by means ofthe calculation and the experiment is found. In the end, a design example of angletransducer circuit is given.
