• ### Inaugural address. The twin pillars of engineering

Publication Year: 1978, Page(s):1 - 7
| | PDF (1329 KB)

There were many achievements of engineering in the ancient past, and the manufacture and subsequent movement of obelisks is selected as an example. The development of engineering in the UK, based on practice, is traced through the Industrial Revolution, together with the rise of technological education. The pattern of education and training was set in the early 20th century and based firmly on the... View full abstract»

• ### IEE Electronics Division: Chairman's address. Quality and reliability in a telecommunications system

Publication Year: 1978
| | PDF (827 KB)

User satisfaction with a public service is a highly subjective matter. It can be influenced by many factors, a high proportion of which are not under the control of the provider of the service. Techniques for gauging it are widely employed, but, for the purposes of system planning and equipment design, more objective - and hence quantifiable- criteria must be used. The Address deals with two of th... View full abstract»

• ### Inductive detection of buried services

Publication Year: 1978, Page(s):14 - 15
| | PDF (251 KB)

A commonly used instrument for finding buried metal pipes consists of two coils, a transmitter and a receiver. The principle on which it works is analysed using the idea of earth-returnÂ¿ currents that flow along the pipe and return through the ground. The theoretical predictions are consistent with what is measured. View full abstract»

| | PDF (1172 KB)

Various techniques for the measurement of elevation angles of arrival of oblique-incidence ionospherically propagated h.f. transmissions using a vertical stack of aerials are reviewed. These include single-mode and two-mode analyses, various wavefront analysis methods and Fourier and maximum-entropy spectral analyses. The methods have been applied to experimental data, and although none is complet... View full abstract»

• ### Dynamic ratio quantiser

Publication Year: 1978, Page(s):25 - 29
Cited by:  Papers (1)
| | PDF (632 KB)

An instantaneously adaptive nonlinear ratio quantiser, called a dynamic ratio quantiser (d.r.q.) is described. It enables a wide range of input signals to be quantised with a nearly constant signal/noise ratio (s.n.r.). The d.r.q. consists of an instantaneously adaptive nonlinear element EL, whose output samples are a function of the ratio of the input and the feedback samples. Theoretically, EL w...

• ### IEE Power Division: Chairman's address. Power-station construction in the UK: which way for the future?

Publication Year: 1978, Page(s):33 - 36
| | PDF (796 KB)

In the first few years following the Second World War, the maximum size of generating units was 60MW. There was a rapid growth in the demand for electricity, and as a result there was a hectic period of design and construction of larger units. Within a period of about ten years, units of nine different sizes were introduced. Not surprisingly, there were many teething troubles, and the availability... View full abstract»

• ### Generalised computational method for reliability analysis of electric power installations

Publication Year: 1978, Page(s):37 - 40
Cited by:  Papers (2)
| | PDF (533 KB)

The paper presents a general computational method together with the relevant computer program which can be easily used to perform reliability analysis on electric power installation configurations. The mathematical reliability model of the program is based on the concept of frequency of failures during the useful life period. In other words, it starts from basic configuration component failure-rat... View full abstract»

• ### A.C.-d.c. load flows with realistic representation of the convertor plant

Publication Year: 1978, Page(s):41 - 46
Cited by:  Papers (4)
| | PDF (607 KB)

H.V. d.c. convertor stations contain a.c. plant components which are specified by their relationship with d.c. link parameters and cannot be represented in conventional terms within the a.c. load-flow solutions. In the paper a comprehensive d.c. link model is developed with generality to represent all the plant components and operating conditions encountered in practice. The New Zealand a.c.-d.c.-...

• ### Multiplexed controls on underground trains

Publication Year: 1978, Page(s):49 - 54
| | PDF (970 KB)

As the sophistication of control and monitor functions on modern underground trains increases, so the limitations of the conventional point-to-pointÂ¿ wiring technique become more apparent. To overcome this problem a time-division multiplexing system has been developed for possible incorporation on future London Transport trains. This paper outlines the philosophy and development behind the syste... View full abstract»

• ### Correspondence: New approach to analysis of polarised mho relays under close-up-fault conditions

Publication Year: 1978, Page(s):56 - 58
| | PDF (429 KB)

Under close-up-fault conditions the voltage signal from the faulty phase may not be sufficient to operate the mho relay. A voltage signal from one of the healthy phases, external polarisation, is added, and the relay, in this case, may be called an externally polarised mho relay. The main effect of external polarisation is the variation of the relay characteristic with the power-system conditions,... View full abstract»

• ### Correspondence: Investigations on operation of fully-controlled thyristor convertors

Publication Year: 1978, Page(s):58 - 59
Cited by:  Papers (2)
| | PDF (250 KB)

The available analysis for fully-controlled thyristor convertors does not cover all possible modes of operation. In this correspondence a new mode of operation is suggested. This new mode results in an increased range of operation with continuous conduction. This has significance in the regenerative braking of convertor-fed d.c. drives. View full abstract»

• ### Correspondence: Shorting-coil modulators

Publication Year: 1978
| | PDF (150 KB)

A new approach to power semiconductor circuits is described, which offers the possibility of extending the range of application of presently available power semiconductor devices. This is achieved by employing a technique called 'shorting-coil' switching, in which power flow in a main circuit can be regulated by switching in auxiliary circuits called shorting coils.

• ### IEE Control & Automation Division: Chairman's address. Control and operation of the UK electricity supply system: an account of its development

Publication Year: 1978, Page(s):61 - 65
| | PDF (861 KB)

Over the past few years, control engineers have been increasingly interested in the control and operation of large systems that are usually hierarchical in structure and involve not only the control of parts of a large complex plant and of the plant as an integrated whole, but also of systems of such plants. The national system for the generation and transmission of electric power is just such a s... View full abstract»

• ### Exact model matching of linear time-varying systems

Publication Year: 1978, Page(s):66 - 70
Cited by:  Papers (3)
| | PDF (642 KB)

The paper considers the problem of designing a static or a dynamic controller to match exactly the input-output description of a given linear time-varying system to that of a desired model. The proposed approach is based on the concept of algebraic equivalence, the motivation being that if algebraic equivalence of the closed-loop system and the model is secured then the input-output descriptions o...

• ### Summanry. Novel electro-optical alignment technique

Publication Year: 1978, Page(s):71 - 72
| | PDF (246 KB)

A novel device has been made which orientates a solid object and a collimated light beam relative to each other, in such a way that the light beam and a cylindrical hole in the object are aligned. A nulling technique is used, incorporating an electromagnetic feedback system driven from an optical error signal. A number of configurations of the basic device have been tested experimentally to identi... View full abstract»

• ### Determination of the sinusoidal and dual-input describing functions for a class of single-and double-valued nonlinearities

Publication Year: 1978, Page(s):73 - 74
| | PDF (213 KB)

A method is presented that can be used to evaluate the sinusoidal-input describing function for a class of single- and double-valued nonlinearities. The basic approach is simple and straightforward and may be applied to the determination of multiple-input describing functions. The method is applied to nonlinear devices which naturally produce a discontinuous output waveform on the application of a... View full abstract»
