“…Te reactive power efect on frequency and the active power efect on system voltage are examined in reference [20], when a STATCOM is simulated in an IHPS. Mining power installations that utilize the FACTS have been documented in references [21,22] where an application study of an SVC for improving the power factor and THD in mining complexes is conducted. STATCOM applications in mining are reviewed in references [23,24], compensating quality problems (voltage sags, THD) in an underground mine, and in reference [25] where it is installed to support voltage during starting of an asynchronous machine in low voltage.…”

In the next decade, the demand for copper is expected to grow by 25%, posing a challenge for mining facilities to increase their production by opening new mines or upgrading existing ones. To optimize the electrical infrastructure of mining facilities, the integration of flexible AC transmission systems (FACTSs) can be instrumental in mitigating voltage stability issues that may arise during the installation of new gearless motor drives (GMDs). The purpose of this paper is to conduct a comparative analysis of the dynamic performance of static VAR systems (SVSs) as a means of enhancing voltage stability in mining expansion projects, particularly in the context of the integration of new GMDs into the system. This paper presents a case study of an existing three crushing-line mine configuration that has been upgraded with two new GMD systems. The primary contribution of this research is a comprehensive methodology designed to enhance the stability of a mining system through the integration of an SVS, which includes the sizing of the SVS system, an analysis of costs, as well as a determination of the required installation surface and optimal placement of the SVS within the system. The simulation results conclusively demonstrate the effectiveness of the SVS systems in reducing the voltage drop by 2% upon activation of new GMDs, as well as mitigating the adverse impact of transient disturbances on the system. Specifically, the first oscillation voltage peak value is improved by 3.5%, following a three-phase short circuit of 1 second duration, while overvoltage is reduced by 1% in response to sudden load changes. When compared with the system without an installed SVS, these findings highlight the significant advantages and benefits of integrating SVSs into mining operations.

“…For the coal mine with high gas leakage risk and the deep mines that only have vertical exits, the extremely serious safety accident will happen if the ventilation or lifting device cannot work because of the power failure [1]. Since that, adding the independent emergency power supply becomes the inevitable choice to enhance the reliability of coal mine distribution network and ensure production safety.…”

In order to meet the increasing safety demands from coal industry and mining company, a lead acid and lithium iron phosphate(LFP) battery energy storage based megawatt level multifunctional emergency power station is designed and developed for a famous coal mine in Inner Mongolia, China. The major function of system is: when the local power grid works normally, the developed system will play the reactive power compensation function instead of traditional static capacitor; when the local grid occurs failure, the energy storage based emergency power station will provides stable power to the extremely critical loads of coal mine for at least 30min. Besides, the proposed energy storage system also can play the 'peak shaving' and distributed new energy generation smoothing according to the customer requirement. The This paper firstly describes the system integration design and major functions; secondly introduce the power conversion system design and NI software/hardware based central control unit; thirdly analyzes the solutions for increasing system lifetime including novel harmonics control for charging & discharging and battery regular online maintenance strategy; finally provides the simulation and test results which demonstrate the correctness of system design, software/hardware development and integration. The business value evaluation shows the high market potential of the proposed system in China and worldwide.  Index Terms-energy storage, emergency power station, industrial distribution network, coal mining, safety, power conversion system, reactive power compensation

ABSTRACT:The application of electricity to the mining industry is a distinctive area of both mining and electrical engineering. Power Quality is defined as "any occurrence manifested in current, voltage, or frequency deviations that results in damage, upset or failure of end-use equipment"s. It is common experience that electric power of poor quality has detrimental effects on health of different equipment and systems. The focus on Power Quality problems has recently become one of the important issues in power systems due to fast industrialization and extensive use of nonlinear loads. The Power Quality management is the key issue in electrical power system and industries are facing these issues around the world. As the mining complexes are often remotely located, power is weak and unpredictable. Loads such as continuous miners mine hoists, mining shovels, crushers, etc. are in demand and also sensitive to voltage dips and fluctuations. Voltage dips or sags often causes equipment to trip, which in turn results in lengthy delays with resultant production and revenue losses. In this paper Proportional Controller (PI) controller is implemented using MATLAB / SIMULINK
