• ### Parallelogram theory for solution of distribution network voltage problems by computer

Publication Year: 1983, Page(s):153 - 164
| | PDF (1500 KB)

The application of the theory of voltage regulation on a distribution network to the problem of optimising the various voltage control facilities available is generally assumed to be well understood. However, with complex network arrangements, the wide variety and numbers of distribution transformers, and differing load patterns, a distribution engineer is faced with a major problem when attemptin...

• ### Representation of non-Gaussian probability distributions in stochastic load-flow studies by the method of Gaussian sum approximations

Publication Year: 1983, Page(s):165 - 171
Cited by:  Papers (1)
| | PDF (713 KB)

The stochastic load flow (SLF) is extended to include non-Gaussian long-term¿¿ nodal probability-density-function (PDF) data by replacing each non-Gaussian PDF with a Gaussian sum¿¿ approximation. A series of SLFs (stochastic load flows) are then performed and the results recombined, with the correct weightings, to generate non-Gaussian PDF profiles for busbars and lines of interest. Generally l... View full abstract»

• ### Economic dispatch of active power with constraint relaxation

Publication Year: 1983, Page(s):172 - 177
Cited by:  Papers (7)
| | PDF (732 KB)

The economic dispatch of active power in large-scale power systems is considered and an algorithm for the solution of the problem by means of the sparse dual revised Simplex method is presented. Computational experience with large-scale problems, including dynamic dispatch over several time steps, is given, which indicates that the method has very low memory and processor time requirements and is ...

• ### New technique for optimal reactive-power allocation for loss minimisation in power systems

Publication Year: 1983, Page(s):178 - 182
Cited by:  Papers (4)
| | PDF (627 KB)

The paper presents an efficient method for minimising power losses and for improving the voltage profile of a large power system. This is accomplished by optimal allocation of reactive-power generation in the system by changing generator voltages and transformer tap settings. The problem is formulated as an optimisation problem, suitable for solution by the linear-programming technique. The advant... View full abstract»

• ### Transient stability analysis of electric power systems by the method of tangent hypersurfaces

Publication Year: 1983, Page(s):183 - 193
Cited by:  Papers (2)
| | PDF (1147 KB)

A direct method is developed for investigating the transient stability of power systems, based on the approximation of the stability boundary by tangent hypersurfaces at certain unstable equilibrium points. This is a development of the tangent hyperplane method of Yee and Spalding. It is compared with the hyperplane method by application to three representative systems and is found to give improve...

• ### Steady-state stability of an HVDC system using frequency-response methods

Publication Year: 1983, Page(s):194 - 200
| | PDF (1059 KB)

An HVDC scheme is an amalgamation of both AC and DC components, the behaviour of which is often difficult to describe because of the interdependence of many of the parameters. The response of the DC system is dependent on the AC system and vice versa. The basic scheme controls also include both rectifier and inverter controls, which are basically separate but interdependent. The complete scheme co... View full abstract»

• ### Field optimisation of high-voltage electrodes

Publication Year: 1983, Page(s):201 - 205
| | PDF (622 KB)

Stresses on materials for HV components have become increasingly large owing to the reduction of their size and the worldwide increase in voltage levels. Since the electrical stress depends heavily on geometric factors, critical domains of an arrangement cannot be represented by such simple bodies as rings, spheres or cylinders. The paper describes an algorithm based on the CAD concept for optimis... View full abstract»

• ### Improved input signals to the polarised-mho distance relay

Publication Year: 1983, Page(s):206 - 216
Cited by:  Papers (1)
| | PDF (1276 KB)

The paper examines the polarising signals used in British and Continental distance protection schemes, in an attempt to optimise the resistive reach of the polarised-mho relay, and also minimise the possibility of overreaching during zone 2 resistive faults. Dual and single polarisation schemes are investigated and alternative schemes with improved protection characteristics are suggested. Relay p... View full abstract»

• ### Discriminative response of distance protection in reverse-fault operation

Publication Year: 1983, Page(s):217 - 224
| | PDF (1215 KB)

The paper provides a detailed investigation of the principal properties of distance protection response, for the particular conditions of faults immediately behind the intended zone of protection coverage, and against which the protection is required at all times to discriminate. Based, first, on a nontransient evaluation model and stability indices defined for each earth- and phase-fault element ... View full abstract»
