ADF água aumenta saída pela Estação de Tratamento de 30% (Comsys AB)

The water treatment process features numerous variable-speed pumps to process large amounts of fluids. By optimizing the electrical behavior of pumps controlled by variable frequency drives (ACV) com Comsys ADF Active Harmonic Filter tecnologia, GRYAAB increased the maximum output capacity of these systems by 30%.

“Graças à ADF agora podemos processar 30% mais líquidos durante os períodos de pico de demanda. We also save energy.”
– Roger Rosenqvist, Gerente de Projetos

GRYAAB is the sewage works of the Gothenburg region in Sweden and its treatment plant Ryaverket os among the largest in all of Scandinavia. Central to saving the environment from pollution, os dois requisitos básicos sobre esta infra-estrutura regional crítico são a operação constante e capacidade de tratamento suficiente. Sistemas de backup de energia UPS são cruciais para garantir um fornecimento de energia seguro e estável.

Quando 17 new VFD-controlled pumps were installed at Ryaverket to increase plant capacity, harmonic distortion on the electrical system rose significantly. The resulting overcurrents caused the UPS fuses to melt. This was avoided by running the pumps at reduced speed. This was however a temporary solution since this reduced treatment capacity below demand. Os conversores de frequência são uma fonte bem conhecida de harmônicos potencialmente prejudiciais.

Os principais benefícios | Pump drives:

  • 30% increased plant output
  • Secured UPS performance provides for reliable production
  • Harmonic distortion below threshold values
  • Reduced energy consumption

Challenge – eliminating the harmonics

After consulting Ångpanneföreningen (ÅF), a premier Swedish consulting firm, Ryaverket announced a public procurement process seeking the implementation of active harmonic elimination technology. A meta era recuperar a capacidade de tratamento completo, eliminando os harmônicos. Comsys won the procurement in competition with several renowned companies.

Solution – ADF Active Filter units

O resultado foi a instalação de dois 600 kVA Comsys ADF Active Filter unidades para gerenciar dois transformadores que fornecem 2160 kVA. Houve uma série de características do Comsys ADF solution that led to Ryaverket’s choice:

  • Conexão e sistema de dimensionamento flexível
  • Custos de manutenção reduzidos para outros equipamentos conectados
  • Ambiente elétrico Disturbance livre
  • Redução do consumo de energia diminuiu através de perdas de transformadores

Result – harmonics elimination

The harmonics elimination resulted in an increased max output capacity of 30%.
Além disso, GRYAAB now manages to operate below the threshold value for harmonic distortion (SS 421 1811). The reduced energy consumption and improved environmental performance are welcomed additional benefits.
