  • Chapter – 3 Electrical Protection System
    CHAPTER – 3 ELECTRICAL PROTECTION SYSTEM 3.1 DESIGN CONSIDERATION Protection system adopted for securing protection and the protection scheme i.e. the coordinated arrangement of relays and accessories is discussed for the following elements of power system. i) Hydro Generators ii) Generator Transformers iii) H. V. Bus bars iv) Line Protection and Islanding Primary function of the protective system is to detect and isolate all failed or faulted components as quickly as possible, thereby minimizing the disruption to the remainder of the electric system. Accordingly the protection system should be dependable (operate when required), secure (not operate unnecessarily), selective (only the minimum number of devices should operate) and as fast as required. Without this primary requirement protection system would be largely ineffective and may even become liability. 3.1.1 Reliability of Protection Factors affecting reliability are as follows; i) Quality of relays ii) Component and circuits involved in fault clearance e.g. circuit breaker trip and control circuits, instrument transformers iii) Maintenance of protection equipment iv) Quality of maintenance operating staff Failure records indicate the following order of likelihood of relays failure, breaker, wiring, current transformers, voltage transformers and D C. battery. Accordingly local and remote back up arrangement are required to be provided. 3.1.2 Selectivity Selectivity is required to prevent unnecessary loss of plant and circuits. Protection should be provided in overlapping zones so that no part of the power system remains unprotected and faulty zone is disconnected and isolated. 3.1.3 Speed Factors affecting fault clearance time and speed of relay is as follows: i) Economic consideration ii) Selectivity iii) System stability iv) Equipment damage 3.1.4 Sensitivity Protection must be sufficiently sensitive to operate reliably under minimum fault conditions for a fault within its own zone while remaining stable under maximum load or through fault condition.

  • Electrical Control and Protection System of Geothermal Power Plants
    Orkustofnun, Grensasvegur 9, Reports 2014 IS-108 Reykjavik, Iceland Number 13 ELECTRICAL CONTROL AND PROTECTION SYSTEM OF GEOTHERMAL POWER PLANTS Daniel Gorfie Beyene Ethiopian Electric Power Company P.O. Box 1233 Addis Ababa ETHIOPIA [email protected] ABSTRACT This study explores the use of electrical controls and a protection system in a geothermal power plant for smooth and reliable operation of the plant. Geothermal power is a renewable energy and is also used as a baseload for the supply of electricity in the grid. To fulfil this goal, great measures must be taken in the selection of electrical protection equipment for the different electrical components, such as the transformer and the generator, as described in the report. A geothermal power plant must also be furnished with a proper control system for controlling different components of the plant such as the turbine, the generator, the transformer, the excitation system and other related accessories so that when some abnormal condition occurs in the system, proper action can be taken. 1. INTRODUCTION Energy is one of the most fundamental elements of our universe. The significance of energy is especially vital for developing countries like Ethiopia. On-demand energy in the form of electricity and modern fuels is the lifeblood of modern civilization and is a critical factor for economic development and employment. In 2013, the total installed capacity of electrical power in Ethiopia was more than 2,200 MW, mainly from hydro power plants, with some help from wind and a small pilot geothermal power plant. Ethiopia launched a long-term geothermal exploration undertaking in 1969.

  • A Novel Busbar Protection Based on the Average Product of Fault Components
    energies Article A Novel Busbar Protection Based on the Average Product of Fault Components Guibin Zou 1,* ID , Shenglan Song 2, Shuo Zhang 1 ID , Yuzhi Li 2 and Houlei Gao 1 1 Key Laboratory of Power System Intelligent Dispatch and Control of Ministry of Education, Shandong University, Jinan 250000, China; [email protected] (S.Z.); [email protected] (H.G.) 2 State Grid Weifang Power Supply Company, Weifang 261000, China; [email protected] (S.S.); [email protected] (Y.L.) * Correspondence: [email protected]; Tel.: +86-135-0541-6354 Received: 13 March 2018; Accepted: 1 May 2018; Published: 3 May 2018 Abstract: This paper proposes an original busbar protection method, based on the characteristics of the fault components. The method firstly extracts the fault components of the current and voltage after the occurrence of a fault, secondly it uses a novel phase-mode transformation array to obtain the aerial mode components, and lastly, it obtains the sign of the average product of the aerial mode voltage and current. For a fault on the busbar, the average products that are detected on all of the lines that are linked to the faulted busbar are all positive within a specific duration of the post-fault. However, for a fault at any one of these lines, the average product that has been detected on the faulted line is negative, while those on the non-faulted lines are positive. On the basis of the characteristic difference that is mentioned above, the identification criterion of the fault direction is established. Through comparing the fault directions on all of the lines, the busbar protection can quickly discriminate between an internal fault and an external fault.
